This actually has a second capacitor which I would assume is a "running" capacitor, what is the function of this capacitor? Is it to reduce surges on the feed voltage due to the nature of this type of capacitor?
This motor is from a Campbell Hausfield compressor. The nameplate states 15 F.L.A, 120 v, Model MC31800AV. It does turn over easily, I had the motor apart and the capacitor covers off and didn't smell anything. As to the centrifugal switch, how does it work and how might I test/evaluate it?
I have a small capacitor start compressor that when last I tried to use it, the motor sounds and looks like it is trying to turn over, but even with no air pressure to pump against won't rotate more than a couple of degrees, and will trip out the circuit breaker after only about 5 seconds. It...
