Another air compresser problem
Well i have a Porter Cable mo#cffn251t pancake compressor that stopped working. I was using the nail gun and when pressure got low the motor kicked in to refill but the motor would not shut itself off so i unplugged it. After the fact i started to smell overheated motor so i figured maybe the motor blew. I let the unit cool down for a couple hours and tried to use it again but the motor wont even come on now, its completely dead.
I opened the unit to have a look around, the fuse inside is fine. Iv looked at the motor for hours and cant seem to find what the problem is. I did read somewhere that some have breakers inside that can trip but had no luck finding one on this unit. Any thoughts, am i missing something here, also is it possible the on off switch can faulty? Sucks cause this unit is a little over a year old and iv become very attached to it lately.

look on the motor data plate for the words "thermally protected".
If it does say that, and it most likely does, there are either thermal fuses or a thermal switch inside the motor.
do you have an ohmmeter or continuity tester?
plus, there should be a description of what type of motor this is. post that as well.

Your AC power supply may have an upstream bad [high resistance] connection that prevents the motor from getting its rated voltage when it needs it.
