Default Repair my Emglo AM78-HV4V air compressor

The only thing I can think of is the unloader (if your compressor has one).
If it's sticking, there may be too much back pressure, and the motor isn't
powerful enough to overcome it.

Like others, I cannot think of anything beside the cap.

We were using our Emglo and shut it down for a lunch break. When we

back and tried to start it again all we got was a load electrical hum

sometimes it would pop our 15 amp breaker.

I pulled the compressor/electric motor unit loose from the rest of the
compressor so I could get to its guts. When I turned the fan blade by

hand
(it turned very easily) I could hear the compressor piston working. I

even
connected the AC power back up but still heard the hum. When I gave the

fan
a twist the motor started running the compressor. However, the motor

won't
start the compressor on its own.

I tried a quick test of the start-up capacitor with my multimeter and it
appears to be OK. It slowly climbs in ohms until infinity. Reversed

the
probes and it does the same thing. Sounds like the capacitor is OK to

me.

I wanted to pull the electric motor loose from the case so I could see

the
brushes and rotor. I removed all the mounting screws from everything I
could see, but I can't seem to pull the unit apart to get to the motor.
Everything is loose and I can twist the case a few degrees, but I can't

pull
it apart.

Anybody know how I can get the motor out so I can look at its guts. Any
help is appreciated. Pretend I'm a dunce and be pretty specific.

Thanks,
Mike
