919.165570 motor hums/buzzes when plugged in
by Jerry Staub
I have a Craftsman upright air compressor, model no. 919.165570. This compressor is more than several years old and has done me well up to this point.
One day, all of a sudden, it just started to hum/buzz when plugged in, which it is still doing.
I unplugged it for a couple of days to let the motor cool off and let the overload switch supposedly reset, according to the manual I have.
I have never taken the shroud off to inspect the motor; by the way, what kind of screws hold this shroud on. I cannot tell by the manual, it only gives a part #. I'd like to repair the problem myself, but maybe not ! Any suggestions ?
