Vibrating excessively

Continuous or excessive vibrating in the blower is a symptom of having issues with the blower’s impeller or fan. A broken fan blade can cause a vibrating sound while the blower fan spins to create airflow.

Sometimes, debris and dirt clog up the fan blade and damage it. You can easily clean or replace the congested blade to eliminate this excessive vibration.

The blower doesn’t blow air

If your DeWalt 20v leaf blower is running but does not blow air, there might be a problem with the fan, impeller nut, or tubes.

The impeller or fan blades need to rotate to provide airflow. Dirt and debris clogging up the fins or blades can cause malfunctioning in the fan. And it may prevent the impeller fins from spinning and blowing air.

Besides, the blower fan is attached to the crankshaft by an impeller nut. So when the impeller nut gets loosened, the crankshaft may spin or rotate without moving the impeller. This also leads the leaf blower to run but not blow air.

Visually check the following parts. If there are any damaged parts, try replacing them to solve the issue.

The Blower Keeps Shutting Off

 The Dewalt 20v blower won’t stay on when there is an electrical short circuit. Failing or damaged battery and/or low power can cause the motor to stop working.

However, if the Dewalt 20v blower stopped working, check if there is any interrupted power supply or not. Fix the damaged wires and connections to prevent your leaf blower from shutting off unexpectedly.

Dewalt 20v Blower Making Rubbing or Clicking Sound

Loose impeller nuts can create loud noises or rubbing sounds. You can easily replace the faulty impeller nut if needed.

A defective flywheel magnet is another potential cause behind a leaf blower making a clicking or rubbing sound. Replace the flywheel to fix this problem.

The Battery Won’t Charge

Another big issue many users face is that the blower battery won’t charge. Well, it can happen for many reasons. First, check if the red charging light is illuminated after inserting the battery into the charger.

Check the current by plugging an appliance into the receptacle. Make sure you have plugged the battery charger into a working outlet.

The Leaf Blower Won’t Start at All

If your DeWalt 20v leaf blower is not starting, visually inspect the battery level. Most of the time, the leaf blower battery loses wattage due to overuse. 

However, your leaf blower battery may need a long charge, or you can also try out a spare battery if you have one. It might help.

Besides, inspect the battery installation and the charging requirements.
