Hello. I just picked up an air compressor that belonged to my stepfather. It hasn't been used in a few years. I plugged it in before I transported it home to make sure it would run and build air pressure, I didn't run it for long because I figured it needed new oil. I get it home and changed the oil and cleaned out the air intake filter. It will run for about 3 minutes before it trips my 20 amp breaker. The motor says 15 amps so I thought it should be good. I am guessing the motor is probably bad. Bad news is that it is a discontinued part and the cheapest I can find a similar motor is $200. Not sure if it is worth the $200 to fix the compressor. Does anyone know any place where I could possibly find one cheaper or get this one repaired? It is a 3.5hp 15 gallon air compressor model number 919.176430. The motor is a 3.5hp GE model 5KCR48TR1W, part C-MO-3019. Next question if replacing the motor isn't an option would it be safe to run it on a higher amp breaker? I don't have one I would have to get one installed. Thanks in advance for any help or advice on the matter.
