After 3 years of planing anything I put through it, my Dewalt 735 13” planer is now tripping the circuit breaker. It typically will start, but if I then turn it off, and on, it will trip the 20A breaker in my shop panel (nothing else on this circuit) with no load (no wood to chew on). Opened it up and there’s nothing stuck in it and the cutter head turns ok.

I have changed the blades and they’re reasonably sharp, so it’s not overheating. It will do this from a cold start if you power it up for a few seconds, then try to power it up again.

I’m thinking that maybe this is a faulty brush in the motor. Anyone else have experience with replacing the brushes in these? Do they behave like this when they need to be changed?

Brushes and bearings are really the only thing that can go wrong with a motor, if you haven’t burned it up.

Sounds like it will probably be the brushes. Not a bad idea to change them after 3 years. It’s a cheap first
step.

You might try swapping the 20amp breaker in the panel with another. Breakers can wear out.
