Question:

Why doesn't my AC electric motor not start when I plug it in?

I have an air compressor AC motor and when I plug it in, it acts like it's not getting any power at all. My thoughts are the the reset switch on it is broken. Could that be it, or could the windings on the motor be bad?I've already replaced the start and run capacitors, so those work. The reset switch just seems to be in bad condition. If so, is the reset switch a special kinda one? And where could I get one?

Answer:

Some electric motors have a governor device on them to automatically switch from the starter capacitor to all ac. Those switches can go bad and will cause this type of problem. If it is the reset switch, or any other type of switch, good luck in finding one. I have these switch issues at work and can not find them. Had to replace the whole motor. Good Luck
why don't you use a multimeter to ohm out the windings that will tell you if they are still good. As far as a reset switch you may have to check with the maker of the motor to get one.
