My air compressor quit working while I was using it (more specifically the electric motor quit). Don't know why. I was using an air tool and it just never came back on when the pressure got low. But it did get pretty hot (not smoking but hard to hold my hand on it). It is a 3 HP, single phase 230V., 1740 RPM, 184T frame, "Farm Duty" Lesson. I bought this compressor used 3 years ago. No history on it. First - I'm real stupid. I didn't actually test for voltage but . . . 1) the reset button was not popped out (but maybe felt like it doesn't have much range of movement). 2) the breaker did not trip. 3) The pressure switch is working and there is continuity through the switch 4) It gets hot as soon as I turn on the breaker. 5) I replaced the bearings about a year ago. It was remarkably clean inside then. 6) I just opened it up (expecting to see melted stuff) and it all looks clean and normal. No indications of heat. Capacitor looks good with no budges or discoloration. Closest place that actually works on motors is 40 miles from here and I don't know their turn around time. Probably longer than I want to wait (I want it fixed now)! Any ideas or things I should check (besides voltage to the motor) - which I will go do right now. Thanks!!!
