Why Miter Saw Stopped Working? Know the Reason Behind It

Has your miter saw stopped working all of a sudden without any apparent damage? Or your miter saw won’t turn on?

This is a common problem for all miter saw users. I have also faced few problems with my Dewalt miter saw that I have been using for the last 4 years. So I have done many Dewalt miter saw troubleshooting. 

As the structure of all miter saws and are similar, their issues and remedies are also almost similar.

Most of the time basic troubleshooting solves the issue. However, you might need to change some parts if they are worn out.

Here, I’ll discuss the common reasons for this problem and ways to solve it. I will be answering some FAQs as well. Let’s get started!

First, try troubleshooting following the miter saw manual below-

Check if it’s plugged in

This is quite common in workshops and outdoors. Craftsmen unplug the saw after finishing using it for precaution. But later forgets to plug it in.

I know this sounds funny but trust me it is the most common mistake. So make sure your miter saw is plugged in properly.

. Vet the circuit breaker

If your saw doesn’t start after plugging in the saw, go over the circuit breaker.

You might have experienced your lights of the house getting dimmed while using the miter saw. This is because miter saws draw a high level of power. For this, the circuit breaker might trip while using such saws.

If you see a breakdown of fuses, replace them or reset the circuit breaker. It is easy to replace a fuse. And only requires a screwdriver and a piece of wire.

. Look over the power cord

The power cord is the thick wire that transmits electricity to your saw from the socket. Check if it has any external damage or not. If you see any blotch, replace it immediately.

. Dissect the carbon brushes

Carbon brushes are vital parts of power generated saws. You can find the brushes opening the motor end cap with a screwdriver. 

There are two of them inside a miter saw. They supply power to the armature. 

They wear out quite often as they are in close contact always. 

If the thickness of the carbon brushes is less than 1/8 inches, change them. These carbon brushes are easily available in the market. 

These were some of the basic remedies that you can follow if your miter saw stopped working. This should fix the issue.

However, you might have to go deeper into the saw to fix some problems. Let’s try to fix a few such problems by answering some FAQs.
