Dewalt planer won't turn on

Broken Contact Switch

Contact switch problems are the most common problem with any power tool.

The contact switch on a Dewalt planer is located near the blade and it is connected to the motor.

When you push the ON button, it makes contact with two spring-loaded pieces of metal that touch together when pushed in.

When you release the button, it is spring-loaded and pops back out. When your Dewalt planer won’t turn on, the problem is likely a worn or broken contact switch.

To fix this problem, you need to take it apart and replace the contact switch.

In most cases, a broken contact switch is a real culprit your Dewalt planer won’t turn on.

Replacing the contact switch is a relatively easy repair that can be done with a few tools.

Once the old contact switch has been replaced your Dewalt planer should now be operational.

Blown Fuse

A fuse is a safety protection device.

It is a small component that prevents electrical current from running through the circuit when it exceeds a certain voltage.

Fuses are made of metals that melt at high temperatures. When the fuse melts, it stops the flow of current and protects the circuit from damage.

To replace the fuse in your Dewalt planer, flip the machine over and remove the screws from the bottom. Remove the cover plate and set it aside.

Locate the blown fuse on the circuit board inside the casing. Unscrew it from the board.

Replace it with a new fuse and screw it into place.

Tripped Circuit Breaker

Circuit breakers are designed to protect your DeWalt planer from electrical overloads.

If your circuit breaker trips, you’ll need to reset it before you’ll be able to turn on your DeWalt planer.

To do this, locate the main circuit breaker and make sure that it’s off.

Then flip the switch back to the “on” position. Now you’ll be able to turn on your DeWalt planer.

Defective On/Off Switch

A defective on/off switch can be a frustrating issue when trying to operate a power tool.

In the case of a Dewalt planer, if the on/off switch is not working correctly, the planer will not turn on.

There are a few potential causes of this problem, including a loose wire, debris inside the switch, or a broken switch.

The first step in troubleshooting the issue is to check the condition of the wires leading to the switch. If they are damaged or frayed, they will need to be replaced.

If the wires look in good condition, then it is likely that there is debris inside the switch that is preventing it from functioning properly.

In this case, it may be necessary to remove the switch and clean it out. In the worst-case scenario, if the switch is broken, the planer will need to be replaced.

The Power Cord is Damaged  

If the power cord is damaged, the Dewalt planer won’t turn on. The first thing you should do is check the power cord for any signs of damage.

If you see any frayed wires or cracks in the cord, it needs to be replaced. You can buy a replacement power cord at most hardware stores.

If the power cord looks fine, the problem may be with the outlet. Make sure that the outlet is working by plugging in another device.

If it still doesn’t work, you may need to call an electrician to check the wiring.

Dust and debris

If your planer is not working, you should check the dust collection system first.

If there is a lot of debris on the blades or in other areas, it may be interfering with the planer’s performance.

You will need to take care of this problem before you can use the planer again.

If your dust collector is not working, or if it is missing altogether, you should get a replacement as soon as possible.

Obstructed Parts

Lastly, if your planer still won’t turn on, check for any obstructions in the moving parts.

Sometimes small pieces of wood or other debris can become lodged in the machine, preventing it from working properly.

Be sure to clear any obstructions before trying to use the planer again.

Possible obstructions:

  • A clogged dust port.
  • A blockage in the blade path.
  • A jammed band saw blade.


Dewalt is known for their high-quality power tools and if your DeWalt planer won’t turn on there are a few things that you can do to try and fix the issue.

First, make sure that all of the wires leading to the switch are in good condition and free of debris.

If there is any damage, it may be necessary to replace the switch. If the power cord is damaged, it will not turn on.

If the obstruction is found in one of the moving parts, it will need to be cleared before trying to use the machine again.
