Dewalt D55146 does not start

i went to use my dewalt today and it would not start. I have had it for at lease eight years.

After further investigation, I notice grass and debris in the motor area.

I took the motor / compressor off the frame. then I took off the motor / compressor housing and found a significant amount of grass and debris in the area.

I removed then observed a severed wire attached to carbon brush.

I proceeded to solder the severed wired, but still had a problem. Then I measured the ac voltage on the switch off 0 on 115. then measured to input of motor off 0 on 115. but still motor does not start. any ideas?

Could easily be a brush problem. Did you actually check them?

If the rotor is exposed, there could be junk in there preventing contact with the armature, or they may just be shot.

DeWalt oil-less d55146 won’t start

DeWalt oil-less d55146 won’t start.

Turned it on one night and just heard a click. No start. Ran very well a couple of week ago. Only use at home for flat lawn mower tire/low pressure on my truck. Wanted to start using air tools to work on my car.

Can you help.

Thanks ,

Sounds like maybe a breaker (probably on the motor) popped.

See the section here on why compressors won’t start and come back if you still have questions.


Capacitor or motor contacts-click sounds like capacitor
