My shop compressor has been flaking out lately.
I accidentally left it on for a few days, and when I came back, the breaker was tripped.
About every third time it started, it would trip.
I first though it was the unloader valve- stuck maybe, but I removed it and left the tank open, and after about three starts-
It hums but wont start unless I spin the pulley.
If it was hard to spin, I'd suspect the pump, but I'm thinking start cap.
The motor has two caps. How do I know which is which? They are not labeled.
Motor is AO Smith 7 159846 02. Can't find anything on 5 pages of google results.
Thanks.
