DeWALT 20v Blower Problems

The best blowers for blowing leaves on the market for producing a high maximum air flow are the range of hand blower made by DeWALT. Even the best tool, though, occasionally fails. Be aware of the major DeWALT leaf blower 20v issues before purchasing or if you already own one.

When using the cordless DeWALT 20V leaf blower, one of the most frequent issues is that it stops operating. But while using this outdoor power equipment, you could also run into additional issues. But the fundamental question is why it occurs and how to remedy it.

They produce well-liked electric blowers that may clean your deck, garage, or yard is the DeWALT 20V leaf blower. This indispensable all-year-round tool is portable, making it simpler to maintain a clean yard.

In our guide, before you discover your DeWALT lawn mower keeps shutting off, you find your DeWALT blower shuts off, among other niggles By the end, you’ll see the most common issues and what you need to do to fix your handheld blower. (Read John Deere Fault Codes List)

DeWALT Leaf Blower Will Not Start

It’s likely a power issue if your electric leaf blower won’t start and blow leaves, which is bad if you have a large yard. Check your fuse box or circuit breaker to make sure the outlet is receiving power and make sure it is plugged into an outlet.

Before trying to start the blower once more, you might need to push the “Test” and “Reset” buttons on your outlet’s ground-fault circuit interrupter (GFCI). Take your blower to a servicing facility if it is receiving power, but still won’t start.

If issues persist or you use a corded blower, try a different power outlet or extension cord to rule out a power problem. A voltage tester can check the power switch’s contact, which may also be the source of the issue.

Troubleshooting A Cordless DeWALT Leaf Blower

DeWALT Battery and Charger Troubleshooting

The DeWALT 20v blower problems are like the drawbacks of other cordless tools including their batteries and chargers. The ease of these quality battery-operated handheld blower options is well known, but batteries and chargers fail, and getting rid of these things is a hassle.

DeWALT battery chargers are quality, but occasionally they may malfunction, causing your batteries to eventually drain quickly. Try charging a new battery and comparing the results to an old battery to see if the DeWALT charger needs to be replaced.

Check the battery life when using a handheld blower, and if necessary, let the blower charge for an extended period. Try starting it on and connecting it to a socket. If it does, your handheld blower battery might not start the engine on its own because it has lost wattage from excessive use.

Try testing voltage or capacity instead of using a voltmeter if your battery is externally charged. Better still, try putting in a spare battery in your battery blower to see if that works. You should also check the battery installation, as it won’t work if the contacts don’t touch.

DeWALT Battery Charging Procedure

The following is the proper way to charge your batteries:

  • Battery discharge when used normally. When you see the tool is losing power, remove the battery.
  • Do not tape the trigger in the ON position.
  • To get the battery to room temperature, let it sit outside of the charger for at least 2 hours.
  • Place the battery in the charger overnight to give each cell a complete charge (A minimum of 8 hours at room temperature).

If there is no variation in run-time, the battery has either totally drained, run out of life, or sustained irreparable damage. Therefore, the battery needs to be changed in any scenario.

Leaf Blower Battery Won’t Charge

When the red charging light turns on, place the battery into the charger. If the battery is dead, charge it for up to 8 hours.

  • Connect the charger to a functional outlet.
  • By inserting an appliance into the receptacle, you can check the current.
  • Ensure the outlet is connected to a light switch that turns the power off when the lights are turned off.
  • Move the charger and handheld blower tool to an area where the surrounding air temperature is at least 40 °F (4.5 °C) and no higher than 105 °F (40.5 °C), and there is a working outlet.

How You Reset a DeWALT Battery

DeWALT lightweight cordless leaf blowers eliminate the need for electrical extension cables by using a rechargeable nickel-cadmium battery pack.

The battery packs are long-lasting and quick to charge, but they have a microchip that turns them off if they get too hot.

You must restart the battery pack when it switches off. The microchip’s memory is erased during the reset operation, giving the chip the green light to charge like a fresh battery. (Find the Best Riding Snow Blower)

To reset your battery:

  • To remove the battery pack from the DeWALT power tool, press the battery pack removal button on the rear of the tool’s handle.
  • Slide the battery down the rail track on the power tool’s base.
  • With the metal contact side facing the metal contacts in the charger, insert the battery pack into the battery pack charger.
  • Give the battery pack eight hours to charge until fully charged.
  • You’ve just reset your DeWALT battery pack.

It is rare for damaged wires anywhere around the battery as it works by contact. However, some models may have damaged wires in the harness if it is backpack-style leaf blowers.

An interrupted power supply can cause the blower speed to speed up and slow down. You will need to replace any broken wires.


The impeller, another name for the fan in your handheld blower, contains many fan blades that direct the airflow as it is spinning to produce it. These fan blades can break now and again, and a broken fan blade can cause excessive vibration.

Some leaf blowers have a vacuum attachment. As a result, the fan blades can occasionally be damaged by dirt and debris being sucked up into them. The fan blades may become dirty over time, increasing vibration, which is a widespread problem with lots of use.


In most cases, neither typical use nor normal wear will cause significant vibration from the washers in your leaf blower. Losing a washer, however, may cause excessive vibration of other components like the isolators or impeller.

When a leaf blower is disassembled, washers can occasionally be put in the wrong spot. There may be increased vibration because of this.

DeWALT Handheld Blower Making Rubbing Sound in Blower Fan

You should examine the housing, washers, flywheel, or impeller nut if your handheld blower fan is making a clicking, rubbing, or loud noise.

Using our repair and symptom guide, you can more accurately determine the part that has to be changed and how.

Consult the manufacturer’s manual if your model requires special repair instructions. If, for example, you purchased a larger quality model, you could find the DeWALT 60v blower problems are often the same, yet they take longer to manifest. (Find the Best Battery Powered Leaf Blower)

DeWALT Leaf Blower Doesn’t Blow Air

In most cases, if your blower won’t blow, examine the impeller nut, fan, and tubes.

Your leaf blower instructions may call the impeller a fan. As above, a fan attached to the crankshaft delivers airflow. Your leaf blower’s fan has fins that move air.

Occasionally, rocks and debris can harm these fins, and damaged fins will stop the fan from blowing air.

The leaf blower’s tubes direct air flow: in some models, the tubes funnel air to a nozzle that boosts airflow. However, it can seem that the blower isn’t blowing air or isn’t blowing enough air, and if you have missing or damaged tubes, they cause this.

Some leaf blowers allow you to redirect airflow via the blower housing, allowing it to serve as a vacuum. However, if your blower isn’t blowing air, it may be misconfigured.

Leaf Blower Dies At Full Throttle

A slightly clogged leaf blower air filter can cause the engine to start but die at full power. Over time, dirt can accumulate in the air filter and choke the engine.

As clogged, the air filter let’s just enough air into the engine to idle, but it shuts down when you speed up.

A clogged air filter might also cause a harsh blower operation. Therefore, air filters should be cleaned as part of your regular blower maintenance regimen.

Likewise, a muffler reduces leaf blower engine noise, and a spark arrestor stops engine sparks from starting the blower and igniting.

Leaf blower exhaust gases enter the muffler and spark arrestor through the exhaust port. Over the life of your blower, carbon deposits from the engine exhaust can be deposited in the muffler and spark arrestor screen.

If the exhaust port, muffler, or spark arrestor is clogged with carbon, exhaust gases can’t leave the engine.

This can cause full-throttle engine failure. In addition, deposits can build up over time, so you should clean your muffler/spark arrestor during your tool’s periodic maintenance. (Read Where Are Husqvarna Chainsaws Made)

Do’s and Don’ts of Using A DeWALT Battery

Please use genuine DeWALT batteries to ensure safe compatibility with DeWALT tools and chargers and the best possible performance.

Increase DeWALT Battery Life

As soon as you see a noticeable loss of power from the tool, stop using the battery. A battery could be damaged if it is completely discharged.

To prevent draining the battery, avoid taping the trigger. (this could void your warranty)

The battery is affected by temperature. Batteries won’t accept a complete charge if they are too hot (105°F or above) or cold (below 40°F).

Outside the 40°F-105°F range, charging batteries might cause a permanent runtime loss, shut down unexpectedly, and won’t blow air.

A chemical reaction occurs when batteries are charged and discharged. If the environment is excessively hot or cold, the chemical reaction is disrupted, resulting in a loss in run-time.

Transport carefully. When transporting batteries, fires can be caused if the battery terminals unintentionally contact conductive materials like keys, coins, and tools.

Anytime you transport individual batteries, ensure the battery terminals are shielded and securely insulated from materials that could encounter them and cause a short circuit.

DeWALT Blower Engine Rpm’s Too High

Check the fan, impeller, rod, or governors if the blower motor RPMs operate too high. The major causes of this are listed below.

Broken Fan Blades

Your blower’s fan, known as an impeller, rotates to draw air into the blower and is powered by the motor. Your blower tube directs air through the housing side and pulls it toward the front of the blower.

The fan’s blades can break off in multiple places, increasing the engine’s RPM. Throughout the blower’s lifespan, debris may unintentionally be pulled into the fan blades, which may cause their breaking.

To help prevent this problem, remove debris entering the blower housing. You will need to replace a broken fan as there’s no way to fix it, and it won’t blow effectively until it has been changed. (Read DeWALT 20v Blower Problems)

Broken Impeller

Your leaf blowers impeller is essential to its efficient operation. The impeller rotates to draw air in, at which time it is directed into the blower tube.

Your engine’s RPM may be excessively high because of a broken impeller, typically brought on by debris harming the fan blades and entering the blower housing. Ensure the blower housing is free of debris to lessen the possibility of your impeller blades failing.

Loose Rods

With a vast, wheeled blower powered by a 4-cycle engine, a rod connecting the throttle control to the governor’s arm is present. No of the circumstances, the governor will control the engine’s speed.

To keep the speed, the governor will open the throttle further when the going gets tough.

The governor won’t be able to regulate the throttle if the rod connecting it to the governor becomes damaged or becomes loose. So, your engine RPMs may run too high because of this.

dewalt, lawn, mower, troubleshooting, blower

Faulty Governors

A large, wheeled blower (looks like a lawn mower) damaged by a 4-cycle engine may have a broken or incorrectly set governor. Your leaf blower’s governor is made to keep the desired speed constant.

It works with the throttle to manage that speed. Your engine’s RPMs may run excessively high if your governor is set incorrectly.

Higher-than-normal engine RPMs might be caused by a damaged governor or governor’s arm.

DeWALT Battery Not Charging (6 Easy Fixes! – Updated)

If you are having trouble with your DeWALT battery not charging, don’t worry you’re not alone.

As with all batteries, DeWALT batteries often go through issues that do not allow them to charge properly. Lucky for you, there are 6 simple things to try before you go out and get a new battery.

Make sure outlet you are using is working

If your DeWALT battery isn’t charging, the easy fix is to ensure the charger’s plugged into a functioning outlet. Plug a different device into the outlet and make sure it works. If the outlet’s defective, try a different outlet and see if charger lights come on when battery is plugged in.

This sounds incredibly simple, but often times it can be the case. It could be that a fuse was blown or the outlet is damaged. Do not overlook this step, it can save some time and effort.

If the outlet is not working, it will not provide power to the charger, and therefore, the battery will be unable to charge. So check the outlet by plugging in another device such as a phone charger to ensure you are getting power.

So you determined the outlet you are using does in fact work, however, the battery is still not charging. Luckily, we have other ways to fix the problem:

Make sure the charger is working: Try another battery

While the charger is plugged in, try a different DeWALT battery. This will quickly determine if the problems with the particular battery or if the charger is not working.

When you plug in a different battery, if the lights on the charger appear, this tells you that the charger is working. So now you know the issue is with the battery.

If using a different battery and you still don’t get indicator lights on the charger, this means the charger is the issue. It is rare but you also could have two faulty batteries.

If the issue is with the charger, I recommend you reach out to DeWALT as most equipment comes with a 3 year warranty.

You determined that it is indeed an issue with the battery and not the charger, then continue on to the next fix.

Press the button on the battery when plugging in

You must press the button on the battery, as it slides down the charger. This ensures there’s an appropriate connection between the battery and charger terminals. You will still get a solid red light on the charger if this is done incorrectly, however, the battery isn’t charging.

As seen in the picture, there is a yellow button on the battery (color will vary depending on battery type). This is the same button you press to remove the battery from a tool. It is essential that you press this button when sliding the battery down the charger. If it is done right, you should hear an audible click, this will indicate that the battery is on properly.

If this is not done properly, then the battery will just be resting on the charger. When this happens it will give the appearance that the battery is fully charged. There will be a solid red light showing on the charger (just as appears when it is indeed fully charged).

What happens in this scenario is that you think the battery is fully charged, so you go and use it, but it only lasts a couple minutes. This is a quick indication that the battery has not been properly placed on the charger.

Just a reminder, if the battery is not fully charged, you should see a blinking red light on the charger when the battery is plugged in.

Below is a guide to the charging lights that you will see on a DeWALT charger:

If you are getting an audible click when placing the battery on the charger, and you find the battery is still not charging, don’t panic. We have a few more fixes to try.

Clean the connections of dirt and debris

If there is dirt on the terminals of the battery and or charger, this will not allow for a good connection. This interruption in the connection will not allow the battery to charge.

The terminals seen above, on both the battery and charger must be clean and free of debris in order to maintain a solid connection.

Often the debris will be visible (dust, corrosion, dirt, etc). However sometimes they may appear clean but in fact there is enough “gunk” in there to disrupt the connection.

It is important, if the terminals appear clean and nothing is standing out, “STILL DO NOT SKIP THIS STEP”. There is absolutely no harm in cleaning out the terminals and it may solve the issue.

The terminals on the charger are bigger, and in my experience much easier to clean. I use a Q-tip and some rubbing alcohol. You want to make sure you hit both sides of the terminal with the Q-tip.

The terminals on the battery are much smaller and harder to get into. For this I have found either an envelope or sand paper folded over does the trick. You want to use something that will be firm enough to not crinkle or loose its shape when you slide it in the slits. I have also found you can dip the sandpaper or envelope in rubbing alcohol to enhance the clean.

Often if using a white material you will actually see the black soot coming off as you stick it in the slits.

Once you have cleaned all the terminals (on the charger and battery), try plugging the battery back in. You should see a blinking red light on the charger, if the battery is charging.

This is a quick and easy fix that is good to get in the habit of doing every couple of months. No matter where you store the battery/charger, debris will build up. It is important to keep the ports clean in order to maintain a quality connection.

Slowly charge the battery for 2-3 minutes at a time

If a battery gets below a certain voltage, it can become flat. If that is the case, you can try charging the battery for 2-3 minutes at a time for a total of about 30 minutes. You can think of this as a way to jump start your battery.

Think of a flat battery as being fully dead. When this happens it cannot hold a charge so by putting it on the charger for shorter bursts will help kick start it back to life. Usually after about 30 minutes of these short bursts, the battery will have enough juice that it can now be fully charged. Again a blinking red light on the charger will indicate if this fixed the issue.

If these 5 fixes have not worked to get your DeWALT battery charging, there is one final thing you can try before contacting DeWALT.

Use speaker wire to connect dead battery to a healthy battery

If you have tried all the other steps and the battery will still not charge. Then you can try and kick start the battery with some speaker wire.

In older DeWALT batteries (that do not have an indicator light) it can be difficult to determine if a battery is fully dead. The best indicator is if you put the battery on a tool and you get absolutely no power. With newer DeWALT batteries that have the indicator light on the front. You can determine a battery is dead if you press the indicator button and no lights come on.

In this case a couple things may have happened. As described above, the battery may have gone flat. Or the battery was so depleted that it went into sleep mode. If this happens, the battery will not even register when placed on the charger. So we need to give it a jump start, just like a dead car battery.

In order to perform this technique, you need to have a fully functioning and charged DeWALT battery.

It is important to note, that on every DeWALT battery there is a positive side labeled “B”, and a negative side labeled “B-“.

Place the two batteries next to each other. Take some speaker wire with the covering removed at the ends so the wire is exposed. Connect the “positive” terminal on the healthy battery to the “positive” terminal on the dead battery (B terminal). Then take a another piece of wire and connect the “negative” terminal on the healthy battery to the “negative” terminal on the dead battery (B- terminal). Make sure that you stick the exposed wire deep in the terminal so it maintains contact with the metal.

Hold the wires in place for 5-10 seconds. That should provide enough “juice” from the healthy battery to jump start the dead battery. Then disconnect the wires. Now try placing the dead battery on the charger. It should indicate that a charge is in progress (flashing red light).

Here is a video on how to use speaker wire to jump start a DeWALT battery:


There are a number of different reasons why your DeWALT battery may not be charging. Luckily, you can try these 6 proven fixes to get the battery charged again:

  • Make sure outlet you are using is working
  • Make sure the charger is working
  • Ensure you are putting the battery on the charger properly
  • Clean the battery and charger terminals of dirt and debri
  • Slowly charge the battery for 2-3 minutes at a time
  • Jump start the dead battery using speaker wire and healthy battery

If you have tried all of these fixes and the battery is still not charging, you should go ahead and contact DeWALT at: 1-800-433-9258.

It is also good to know, most DeWALT products come with a 3 year warranty. You can look up more info on Dewalts warranty policy for further information.

Thanks David, great guide! The “Use speaker wire to connect dead battery to a healthy battery” section saved me a long lost battery that I found and I was about to trash! Never would have thought to try that.

I bought 2 DeWALT batteries on EBAY. One charged right away, the other seemed dead: no lights of any kind on the charger. I jumped it just like you show, and now it’s charging like it should. Thanks.

My battery was reading 3.4v but the charger wouldnt respond to it. Jump start technique worked. Could probably jump it with a 9v alkaline or a 12v Dc adapter also if you don’t have another 12-20v tool battery available. Anything to break it out of sleep mode.

I bought the old type ni-cad De Walt drill a long time ago now (before lithium). I injured my back never got to initially give the DeWALT it’s first charge it never got used for 12 months so it went dead flat and never took a charge. They (ni-cad) were the pole type batteries would it be advisable to kick start that ni-cad with a lithium battery going b to b and the b- to b- on the ni-cad terminals…thanks.

David S says:

Hi David, my TWO 36 volt LI-ION 2.0 AH BATTERIES WONT CHARGE. Neither of them have any charge so I can’t connect the wires to boost the other one. I have 18 volt 5.0 ah batteries so have tried connecting to one of them but this doesn’t work. Obviously I am assuming that the b and b- connectors are the same on both batteries (hope this makes sense). Any other advice as to how to get them to charge?

David S says:

Have you tried doing the short quick 30 second charges for 10-15 minutes? Try and wake one of them up so you can then jump the other.

Hi David S, this all looks helpful although my starting point is that with one of the large DW XR Flex batteries, when I put it into the yellow fast charger (that I’ve always used with it) it seems to be okay for about two minutes (fan is on, seems to be running normally) then it just stops dead. If I try again the same thing happens. Have you experienced anything like this? I’m unsure whether the charger or battery is at fault. The battery has had only light use in the house as a bumper phone charger so things like heavy daily use or workshop dust/sawdust aren’t factors. Any thoughts on this would be great, thanks!

David S says:

Could be the charger so try another battery on there. Also the battery could be in that dead zone that I described above. Try doing those short burst 30 second charges for 10-15 minutes to try and wake it up. Also could try the jump start method with another battery.

My 6 ah flex volt turns red real quick then black. It shows two battery icons on battery but stays lit then slowly fades. But battery still has charge. Just won’t take any charge. I tried all methods

David S says:

Hi David my 20 volt max battery won’t charge red lite just blinks. Have left batteries in charger all night still no charge.

David S says:

Try cleaning the terminal on both battery and charger. If not it may need a jump which you can find how to do in the article.

DeWALT Charger Solid Red Light But Not Charging: What to Do?

If you are reading this, then you have a DeWALT charger with a solid red light and it is not charging. This can be very frustrating, but do not worry, you are not alone.

In this guide, we will walk you through the most common reasons why your DeWALT charger is not charging and what you can do to fix it. We will also provide some tips on how to prevent this from happening in the future.

Different DeWALT Chargers May Have Different Colors

If you have a DeWALT charger that has a solid red light, it is important to know that different models of chargers may have different colors for the solid red light. For example, some models will have a green light instead of a red light.

If your charger has a different color light, please consult your owner’s manual to determine what the light color means. [1]

What Do Those LEDs Mean Already?

The light on your DeWALT charger is an important indicator of the status of your battery. When the light is red, it means that the battery is charging. When the light turns green, it means that the battery is fully charged. If the light is flashing red or green, it means that there is an error with the charger or the battery.

If your charger has a solid red light, it means that the battery is charging. If the light is green, it means that the battery is fully charged. If the light is flashing red or green, it means that there is an error with the charger or the battery. [1]

Yellow Led and Temperature Delays for DeWALT Batteries

When the charger is connected to a power source and the battery is inserted, a yellow light will come on. If this light is flashing, it means the temperature of the battery is too low for charging to start. The battery must be warmed up before charging can begin.

To do this, simply remove the battery from the charger and place it in a warm environment for a few minutes. Once the temperature of the battery has risen, reinsert it into the charger and charging will begin automatically.

If the light remains solid yellow, this means that the charger is running a self-test. This is normal and should not cause any concern. The test takes around 30 seconds to complete and the charging process will begin automatically once it is finished.

If the light turns red after the self-test is complete, this means that there is an issue with the charger or the battery and charging will not commence. In this case, you should contact DeWALT customer service for further assistance.

Is that True for All DeWALT Chargers?

No, it’s not true for all DeWALT chargers. In fact, it’s not true for most of them. The vast majority of DeWALT chargers have a green light that comes on when they’re charging and turns off when the battery is fully charged.

The only time you’ll see a red light on a DeWALT charger is when there’s a problem with the charger or the battery. If you see a red light, it means that the charger isn’t working properly and you need to troubleshoot the problem. [1]

DeWALT Battery Electronic Protection System

The DeWALT Battery Electronic Protection System (EPS) helps to protect your batteries from overcharging, overheating, and deep discharge. When the EPS is activated, it will cut off power to the battery to prevent damage.

  • Overcharging: If a battery is left on the charger for too long, the EPS will activate to prevent overcharging;
  • Overheating: If a battery gets too hot, the EPS will activate to prevent overheating;
  • Deep discharge: If a battery is discharged too deeply, the EPS will activate to prevent deep discharge;

How to tell if the EPS is activated:

The EPS will activate if the battery charger has a solid red light. If the charging indicator light is blinking, this means that the EPS is not activated and the battery is charging normally.

What to do if the EPS is activated:

If the EPS is activated, you will need to replace the battery. You can find replacement batteries at your local DeWALT retailer.

You should also check the charging indicator light on the charger to make sure that it is not blinking. If the light is blinking, this means that the EPS is not activated and the battery is charging normally.

Is Something Defective with Your DeWALT Charger or Battery?

If your DeWALT charger has a solid red light but is not charging, it could be due to a number of reasons. In some cases, it may be necessary to replace the charger or the battery. However, there are also a few things you can try first that may fix the issue without having to replace anything.

If the cord is plugged in securely and there are no obstructions, the next thing you should check is the charging port on the battery. Make sure that there is nothing blocking the port such as lint or dirt. If the port is obstructed, it may not be able to make a good connection with the charger.

If you have tried all of the above and the charger still is not working, it is possible that there is a problem with the charger itself. In this case, you should check for updates. DeWALT offers firmware updates for its chargers from time to time. These updates can fix bugs and improve performance.

If you have tried all of the above and the charger still is not working, the next step is to contact DeWALT customer service. They may be able to help you troubleshoot the problem or offer a replacement charger or battery.

DeWALT Charger Blinking Fast: What to Do?

If you have a DeWALT charger that is solid red but not charging, there are a few things you can do to troubleshoot the issue. It’s important to note that a solid red light on your DeWALT charger indicates that the charger is receiving power, but it isn’t necessarily delivering power to the battery.

  • Check the connection between the charger and the power outlet. Make sure that the charger is firmly plugged into a working outlet. If you’re using an extension cord, make sure that it is also properly plugged in and that it isn’t damaged;
  • Check the connection between the charger and the battery. Make sure that the battery is properly inserted into the charger and that the connection is secure;
  • Try a different outlet. If you have another outlet nearby, try plugging the charger into that outlet to see if it will charge the battery;
  • Try a different battery. If you have another DeWALT battery, try charging that battery with the charger to see if it will work;
  • Contact DeWALT customer service. If you’ve tried all of the above and your charger still isn’t working, you may need to contact DeWALT customer service for further assistance;

Troubleshooting a DeWALT charger that is solid red but not charging can be frustrating, but following these steps should help you get to the bottom of the issue

If your charger is still not working after following these steps, contact DeWALT customer service for additional help. [1]

DeWALT Charger Solid Red Light but Not Charging: What to Do?

By following these simple troubleshooting steps, you should be able to get your DeWALT charger working again in no time. [2]

DeWALT Charger- Briefly Explained

DeWALT is a popular charger used to charge up batteries for tools. It is known to have a long life and be very reliable. However, like any other charger, it can have problems from time to time. One such problem is when the DeWALT charger has a solid red light but is not charging the battery.

There are a few things that could be causing this problem. It is important to troubleshoot the charger to determine the root of the problem. Once the root cause has been determined, it will be much easier to fix the charger and get it working again.

One possible reason for a DeWALT charger to have a solid red light but not charge the battery is that the battery is not properly connected to the charger. This can be easily checked by making sure that the battery is properly seated in the charger and that the connections are tight.

Another possible reason for a DeWALT charger to have a solid red light but not charge the battery is that the charger itself is not working properly. This can be checked by testing the charger with a different battery. If the charger works with the other battery, then the problem is most likely with the first battery and not the charger.

If neither of these solutions solves the problem, then it is likely that there is a more serious issue with the DeWALT charger. In this case, it is best to take the charger to a qualified technician for further diagnosis and repair. [1]

DeWALT Charging Lightning Patterns

Most DeWALT power tools come with a charger that has a built-in LED light. This light is used to indicate the charging status of the battery.

There are usually three different colors that the light will be, depending on the state of charge of the battery. The three colors are green, yellow, and red. Here is what each color means:

  • Green: The battery is fully charged and can be used;
  • Yellow: The battery is charging and will be ready to use soon;
  • Red: The battery is not charging and will need to be replaced;
  • The battery may be defective. If this is the case, you will need to replace the battery;
  • The charger itself may be defective. In this case, you will need to replace the charger;
  • There may be something wrong with the power outlet that you are using. You will need to check to make sure that the outlet is working and that there is nothing blocking it;
  • The battery may be too hot or too cold. If the battery is too hot, it will not charge. If the battery is too cold, it will also not charge. You will need to let the battery warm-up or cool down to room temperature before trying to charge it again;
  • The battery may be too old and no longer able to hold a charge. In this case, you will need to buy a new battery;

If you have a DeWALT charger that is not working, you can try these troubleshooting tips. If none of these tips work, you will need to contact customer service for further assistance.

Loose Connections

One of the most common reasons a DeWALT charger may display a solid red light but not charge the battery is loose connections. If the connection between the charger and the battery is not secure, it can cause charging issues.

To check for loose connections, first, remove the battery from the charger. Then, inspect both the charger port and the battery port for any dirt, debris, or damage. If either of these ports is damaged, it could prevent a secure connection and cause charging issues.

Once you have checked the ports for damage, reattach the battery to the charger and try charging again. If the issue persists, try using a different charger or battery. [2]

Battery Not Added Properly

The first thing you want to check if your charger is displaying a solid red light but not charging is whether or not the battery was properly added to the charger. If the battery was not properly inserted, then it will not charge.

To properly insert the battery, make sure that the positive and negative terminals on the battery are lined up with the corresponding terminals on the charger. Once you have done this, insert the battery into the charger until it clicks into place.

If the battery is properly inserted and you are still seeing a solid red light, then there may be an issue with the battery itself.

Incompatible Charger

The first thing you should check if your DeWALT charger has a solid red light but is not charging is whether or not the charger is compatible with the battery.

Different chargers are made for different types of batteries, so it’s important to make sure that you’re using the right one. If you’re not sure, you can check the compatibility chart on the DeWALT website.

Faulty Or Damage Wire or Cable

One of the most obvious reasons for a charger to not work is if there is something wrong with the wire or cable. This can be due to physical damage, such as fraying or cuts in the insulation, or it could simply be that the wire has come loose from the connector.

If you suspect that this might be the problem, then the first thing to do is to check the wire and connector for any visible damage. If there is damage, then you will need to either repair or replace the wire.

If there is no visible damage, then you should try reconnecting the wire to the connector. If this does not work, then you may need to replace the connector.


What does a solid red light mean on a DeWALT battery charger?

A solid red light on a DeWALT battery charger typically indicates that the charger is not receiving power. This could be due to a problem with the outlet, the power cord, or the charger itself. If the light is flashing, it usually indicates that there is a problem with the battery.

How do you reset a DeWALT battery charger?

To reset a DeWALT battery charger, you will need to disconnect the power cord from the charger and then reconnect it. You may also need to remove and then re-insert the batteries.

What can I do if my DeWALT battery won’t charge?

If your DeWALT battery isn’t charging, there are a few things you can do to try and fix the problem. Make sure that the charger is plugged in properly and that the outlet has power.

Check that the connections between the charger and the battery are secure. If none of these solutions work, you may need to replace either the charger or the battery.

How do I know if my DeWALT battery is bad?

  • First, you may notice that it doesn’t hold a charge as well as it used to;
  • Second, the battery may start to swell or balloon up;
  • Third, you may see corrosion on the terminals of the battery. If you notice any of these signs, it’s time to replace your battery;

Why does my battery charger stay red?

  • First, it could be because the charger is not properly plugged in;
  • Second, the charger could be defective;
  • Finally, the battery itself may be damaged and need to be replaced;
  • Make sure the charger is properly plugged in;
  • Check the connections between the charger and the battery to make sure they’re cured;
  • Try resetting the charger by unplugging it and then plugging it back in;
  • If none of these solutions work, you may need to replace the charger or the battery;

My DeWALT charger is green but not working. What can I do?

There are a few things you can try if your DeWALT charger is green but not working.

First, make sure the charger is properly plugged in and that the outlet has power. Next, check the connections between the charger and the battery to make sure they’re secure.

If the problem persists, try resetting the charger by unplugging it and then plugging it back in.

Finally, if none of these solutions work, you may need to replace either the charger or the battery.


If your DeWALT charger has a solid red light and it’s not charging, you have a few options. You can try to troubleshoot the problem yourself or take the charger in for repair.

If you do choose to try to fix it yourself, be sure to use caution as there is risk of electric shock. The best option may be to just buy a new charger because they are relatively inexpensive.

We hope this article helps you resolve your charging issue with your DeWALT battery!


Electric Lawn Mower Not Starting? It’s One Of 12 Issues

Well, wouldn’t you know it? You’ve got the time finally to attack the lawn you’ve been meaning to get to and what happens? Nothing.

Not because of anything you’ve done. No, you’ve planned to get this done.

Yet, regardless of all your planning, your trusty electric mower just won’t start.

Okay, maybe that’s all a bit dramatic. Perhaps you just figured it was as good a time as any to hit the lawn with a well-deserved trim. Or maybe there’s a storm coming through and you wanted to get the mowing done before the grass became saturated for a few days.

Regardless of the circumstances, the main thing is your mower isn’t cooperating, so there’s not going to be any mowing until you figure out what the issue is. That’s the dramatic part.

Just remember, when it comes to an electric mower not starting, whether it’s a corded or battery-powered mower, it will probably be an issue with the power supply (outlet/breaker or battery charger), power transmission (cord or battery), or the mower itself (breakers, connections, motor control switches, etc).

Before you start tearing anything apart in a desperate attempt to get your mower, well, mowing, below are some things to troubleshoot and things to consider that might fix the problem before you have to get a technician or service center involved.

Safety First

First, let’s go ahead and get this out of the way. Always remember safety first when it comes to troubleshooting any kind of equipment that can either cut off fingers or electrocute you or both. That’s a bad day that should be avoided at all costs.

Second, have your manufacturer’s manual (or owner’s manual, whichever you prefer) available. If you don’t have a hard copy, you can probably find it online by doing a Google search that looks like, “[Your Brand] [Model Number] Manual PDF.”

Once you have that ready, you’re ready to start troubleshooting.

Troubleshooting Processfor a Corded or Battery-Powered Mower

Before we get to the specific electric mower you have, the troubleshooting process will follow essentially the same path in this general order:

  • Inspect the power transmitter (the cord for a corded mower and the battery for the battery mower).
  • Insect the power supply (the outlet and circuit breaker for a corded mower and the battery charger for the battery mower).
  • Inspect the power receiving end on the mower.
  • Consult your warranty information and contact service center if necessary.

A Corded Electric Mower

Before we determine what the power issue with your electric mower may be, first it helps to know the type of electric mower you have. In this case, let’s assume you have a corded mower.

Let’s also assume that, until this moment, you’ve had zero issues with the mower when it comes to starting and stopping it or anything related to sources of power.

Now, let’s troubleshoot.

Inspect the Cord

If it is a corded electric mower then the first thing you’re going to want to do is to inspect your cord. As most corded mowers do not come with a manufacturer’s provided cord, you have to provide your own extension cord. It should be a standard 16-gauge grounded cord and free of any cuts or other visible damage. Also, check the prongs on the male end and the female end for damage. Lastly, check the male end on the mower itself.

Inspect the Outlet and Breaker

If you’re satisfied the cord is good, try plugging it into another item from the same wall outlet. If there’s no power at the outlet, then you’ve probably identified the issue. It could be a loose wire, a bad outlet, or a tripped breaker. Check one after another until you find the problem.

Check the Breaker and Motor Control Switch

If there isn’t a problem at the outlet or breaker and the cord successfully powers something other than the mower, then the issue is probably at the mower itself.

At this point, check the connection at the mower again to make sure it’s tight and holding firm.

From here, go to the breaker on the mower itself. Push RESET and see if the mower has power now. If it does, there was your problem. If it doesn’t then you may have a bad motor control switch. At this point, unless you know how to repair or replace such a switch, you’ll probably need to consult a service center or repair technician.

Warranty and Corded MowerTroubleshooting Review

One thing to check that’s not on the mower but applies to it is how old it is and if you still have a warranty on it, whether it’s a manufacturer’s or from the store it was purchased at. If you still have a warranty, don’t do any more work on the mower and place that warranty-issue call to get it fixed.

dewalt, lawn, mower, troubleshooting, blower

That pretty much sums it up for a corded electric motor. If it isn’t starting, check the power supply at the plug and main breaker, the power transmission at the cord, and final the power receiving at the mower itself. Do that in that order. From there, if you can’t identify the problem, time to call for help.

A Battery-Powered Electric Mower

Okay, now if you don’t have a corded electric mower but a battery-operated model, then this section is for you. However, you should still read through the corded mower section because you might pick up on something there that might help someone you know down the road.

Like the corded mower, let’s assume your mower has functioned normally until this moment and, unexpectedly, it’s just not starting.

Well, clearly there’s a power issue of some sort. So, let’s get to troubleshooting.

Inspect the Battery

With inspecting the battery, you should be looking for any kind of visual damages or leaks. Also, check the battery light to ensure it does indicate a charge. It might not be true but check all the same.

While inspecting, also make sure the battery is dry. A damp or wet battery can cause a short, lead to overheating, and cause a breakdown. If you believe this happened, you shouldn’t have a solid charge on the battery at all.

Speaking of charges, if everything looks good, and you have a battery tester, this would be an ideal time to test it. That way, if it’s not showing a charge even though the indicator lights up green, then you know the battery is probably bad and needs replacement.

Inspect the Battery Charger

If your battery is charged and you’ve tested it and you’re confident it is, then your battery charger should be operating properly. However, if you’ve got no charge on the battery after testing it, check the charger to see if there’s an issue there.

One way to test the charger is, of course, to put another battery on it and see if it charges. However, not everyone has extra lawn mower batteries. Really, the only thing you can do here is to inspect the charger for damage, check the outlet, and inspect the breaker as you would do with a corded mower.

Another thing you can do is use a volt meter. A positive result would indicate that a charger is at least supplying energy but the battery probably can’t hold a charge for long. A negative result would indicate that the charger itself is bad.

Store Your Mower in a Dry Place

Another tip that sounds obvious but one that’s very important when it comes to electric mowers. Remember, water can seriously damage an electric mower, especially a battery-operated one.

Store Your Cord and Battery After Use

Don’t leave the cord with the mower where it can get damaged. Store it somewhere it is easy to get to but won’t be affected by things like sharp blades or wheels. You get it.

For batteries, remove them after use and charge them but don’t leave them on the charger all the time. Also, don’t run the battery completely dead all the time. Running a battery to both extremes can diminish its service life quicker than normal.

Visually Inspect the Mower Before Use

Again, it sounds obvious but it’s good advice, especially if you haven’t taken a look at the blades in a while.


When you use equipment that runs on electricity or gas, eventually you’ll have an issue that needs some special troubleshooting attention. The good news is, with electric mowers, it doesn’t take much time to figure out what the issue might be and when you’ll need to call for assistance.

Just remember to always be safe, walk through the steps, and be patient. Electricity is a wonderful thing but it isn’t magic. Be safe and remember to call for help if you need it.

How to Fix CRAFTSMAN Electric Lawn Mower Problems

Every homeowner with a lawn has experienced the occasional glitch on their electric lawnmower from time to time. The CRAFTSMAN electric lawn mower is reliable, but hardworking garden machines experience wear and sometimes require troubleshooting to fix minor problems.

Possible problems your CRAFSTMAN electric lawn mower can experience:

  • CRAFTSMAN electric mower won’t start.
  • The mower cuts out while mowing.
  • Overheating and doesn’t work.
  • Uneven cuts.
  • Losing power.
  • Excessive vibrations.
  • The mower is hard to push.
  • The electric mower trips the breaker.

CRAFTSMAN Electric Lawn Mower Won’t Start

One of the most fundamental problems you can experience in an electric lawn mower is that it will not start. There are several non-starting problems you may experience. The mower may not start when you take it out to mow the lawn, or it can stop during mowing and refuse to start up again.

There may be some crossover for the causes of both these issues, but we will address them separately since there may be different problems causing each issue.

If the mower won’t start right away when you take it out of the shed or garage, but it worked without an issue the previous time you mowed the grass, you should perform a sequence of checks.

These checks will give you the way forward to resolve the problem on your CRAFTSMAN electric mower and get it running again.

An electric mower relies on a connected circuit to deliver power to the motor. If the mower does not start, there is a fault between the power source, the power outlet, and the motor.

The best way to establish the problem is to run through a series of checks to eliminate the possible problems one by one, beginning with the simplest and most obvious and ending with the least likely issues.

The switch will need to be replaced.

If you are unsure how to repair any of these faults, especially problems in the motor itself or switches on the controls, you should take your mower to the nearest service center to have it checked out.

Never open the mower housing or work on switches with the mower connected to the power. This action is dangerous and can result in a severe electric shock!

CRAFTSMAN Electric Lawn Mower Cuts Out While Mowing

If you are using your CRAFTSMAN electric mower and during the mowing, the machine cuts out and will not start, there are some potential issues to check.

Some issues that can cause this problem are simple to check and easy to remedy. There may be some crossover between the causes for this problem and the lawn mower issue of not starting from the word go.

Solution 1: Check the Circuit Breaker

The first aspect to check is whether the circuit breaker has tripped. Circuit breakers do not normally trip for no reason, so if the breaker is off, the problem bears further investigation.

Solution 2: Check the Extension Cable

Check the extension cord for frayed areas or damage. If the extension cord does not look good, try a different extension cord or replace the extension with a new one.

CRAFTSMAN Electric Mower Overheats and Doesn’t Work

Occasionally, an electric mower motor can overheat to the point that the mower cuts out and refuses to work until it has cooled down sufficiently.

Why I’ll never buy another Dewalt 20v tool again Honest Review of Dewalt Leaf Blower

An overheating problem in your mower could be a simple result of working the machine too hard and long on a hot day, or it can result from a maintenance issue that must be addressed.

Solution 1: Let the Mower Cool Down

If the mower has been working for an extended period on a hot day, the mower motor may reach an operating temperature that is outside of its specified safe range. The mower motor will then cut out as a safety measure to protect the motor from damage.

This result is a normal protective measure for the mower, and the only thing to do is to stop mowing and give the mower 10 to 15-minutes to cool down.

Solution 2: Remove Grass Build-up in the Mower

Another cause for overheating in electric lawnmowers is a buildup of grass and organic material under the plastic housing covering the motor.

The only method to clear this problem to prevent overheating is to remove the plastic hood over the CRAFTSMAN motor and clear away the debris. The plastic hood is easily removed by loosening the 3 screws on each side of the plastic cover.

Once the cover is removed, check for debris clogging the vents inside the cover and any accumulation of cut grass under the cover.

The best way to remove the grass buildup under the hood is to blow it away with an air compressor or a leaf blower. Alternatively, the grass can be wiped away with a cloth.

Once the obstruction is cleared, air can circulate freely around the motor, keeping it cool and solving the overheating problem.

My CRAFTSMAN Electric Mower Is Cutting Unevenly

If you notice that your CRAFTSMAN electric mower is cutting unevenly in a single pass over your grass, or there are high and low patches in the cut path, you may have a problem with your mower.

The cut should be clean and even across the entire swath cut by the mower. A worn mower blade is the most common cause of an uneven cut height.

The only solution to this problem is to replace the mower blade. This job is easily done as a DIY project and does not require the mower to be taken to a service center.

When you replace the blade, it is likely that the blasé insulator, a plastic part under the securing nut and spacer, will also need replacement. The blade and the insulator can be purchased from your local mower spares supplier.

Follow these steps to replace the mower blade.

  • Unplug the mower from the power source.
  • Lay the mower on its side to expose the blade.
  • Use an adjustable wrench to loosen the central locking nut on the blade. Use a gloved hand to hold the blade in position and prevent the mower blade from turning when you loosen the securing nut.
  • Remove the old blade and insulator.
  • Replace with the new blade and insulator, positioning both parts in the correct orientation as indicated on the parts.
  • Replace the locking nut and tighten it securely, but take care not to overtighten the nut.

CRAFTSMAN Electric Mower Loses Power

As you mow the lawn or your backyard, you may find the mower losing power when cutting longer grass or generally struggling, and you can hear the motor lose power and speed.

The two main causes for this problem are trying to take cuts that are too deep in thick grass or cut grass, leaves, and debris that have clogged the underside of the mower and are impeding the spinning blade.

Solution 1: Raise the Mower Cut Height

The solution for the first cause is relatively straightforward. Use the lever on the side of the CRAFTSMAN electric mower to raise the level of the cut to the highest setting.

With the cut height lever set to the highest mark, make several passes over the long grass, lowering the cut height a notch after each pass until the mower cuts to the desired length.

Solution 2: Remove Debris From Under the Mower

The second cause for the power loss problem can be debris accumulated under the mower in the blade space. This accumulation of debris can interfere with the spinning blade, causing the mower to lose power.

To fix this issue, ensure the mower is unplugged from the power source, turn it on its side to expose the blade space, and clean out the debris. If the dirt is caked onto the mower chassis and is difficult to remove, a paint scraper can be useful to dislodge the material.

CRAFTSMAN Electric Mower Vibrates Excessively

Experiencing excessive vibrations and shuddering when operating your CRAFTSMAN electric mower can be disconcerting. The cause for the vibrations could be a simple fix, or it may require the mower to be checked out by a service center.

The more serious of the two causes is a possible bent shaft in the motor, while the second and more likely cause is a bent, worn, or loose mower blade.

dewalt, lawn, mower, troubleshooting, blower

Solution 1: Check the Mower Blade for Looseness or Damage

The blade problem is the easiest option to investigate and remedy and should be checked first as the possible cause for the excessive vibrations.

Ensure the mower is disconnected from the power outlet and lay the mower on its side to inspect the blade. Check the mower blade for damage and wiggle it to see if it is loose.

If the blade is loose, simply reposition the blade and spacer and tighten the securing nut. If the blade shows signs of damage or is bent, it must be replaced.

Solution 2: Get the Mower Checked by a Service Professional

A bent motor shaft is another possible cause of excessive vibrations in the mower. This situation is a serious problem often caused by the blade striking a hard, immovable object while spinning at high speed. The impact of the blade on the object can bend the motor shaft.

Unfortunately, a bent motor shaft is not a problem that the mower owner can solve. The lawnmower should be taken to an authorized repair center. In all likelihood, the motor will need to be replaced.

CRAFTSMAN Electric Mower Is Hard to Push

There are times when cutting your lawn that you find your electric mower hard to push and difficult to control.

This issue can be caused by cutting high or thick grass, uneven ground, or soft ground. These situations can make the mower difficult to push and cause the mower to struggle to cut the grass.

The uneven ground may cause the rear of the mower housing to drag on uneven ground, making it difficult to push the mower. Thick grass can also cause drag on the blade, which will make the mower hard to push.

Solution 1: Raise the Mower Cut Height

To make pushing the mower easier, raise the cut height to take a smaller bite of the grass at a time. This strategy will require multiple passes to get the grass to the desired height, but the mower will be easier to push.

Raising the cut height will also prevent the mower body from dragging on uneven ground, reducing the effort required to push the mower.

Solution 2: Engage the Self-Propelled Lever

Some CRAFTSMAN electric mowers come with a self-propelled option, which is engaged by pulling a lever on the mower’s handle. This option will use some power from the motor to drive the wheels, which propels the mower forward, reducing the effort required by the person pushing the mower.

CRAFTSMAN Electric Mower Frequently Trips the Circuit Breaker

A problem you may experience when using your CRAFTSMAN mower is the circuit breaker frequently tripping while the mower is being used.

This problem may be caused by factors external to the mower or a problem with the mower itself.

Solution 1: Check the Extension Cable for Damage

The first check you should perform if your CRAFTSMAN mower frequently trips the circuit is to inspect the extension cord for fraying, damaged insulation, or a fault. This damage is the most common and likely cause of frequent circuit breaker trips with an electric mower.

Replace the extension cord if any wear is noticed on the cable or damage to the exterior of the cable is visible.

Solution 2: Check the Circuit for Overloading

Another cause of the circuit tripping may be unrelated to a fault on the mower or the extension. If the circuit the mower is working on is overloaded with other appliances or devices, the circuit may trip when the mower motor is engaged.

Check for other appliances or power tools on the same electrical circuit, unplug them while using the mower, or consult an electrician to install a larger circuit breaker.

Cutting thick grass may also cause the circuit preacher to trip. The mower will draw more power when pushed through thick grass, and more demands are put on the motor. Raise the cut height when cutting thick grass to prevent this problem.
