Assuming it's a 120V/240V motor connected for 120, can you check to
see if both run windings are actually connected? Perhaps a nut is
working loose on the terminal plate inside the motor.

No load, it's drawing about 1.5 amps. It gets warm, but not as hot as
it was under load.

Hmm, you might have something, there! This motor is probably 15+ years
old, and has never had anything done to it. Could corrosion and/or
loose connections account for the lack of power? I can certainly try
cleaning and tightening anything I can get to.

Thanks!

check the brushes and commutator.

Hi!

You should check the pressure switch contacts to be sure they aren't
burned. If they look OK, check the wiring leading to the compressor.
Perhaps something is wrong there. (Be sure you shut the power off FIRST
or you could have a shocking experience.)

Failing all of that, I'd check to see if the motor uses a run capacitor.
If it does, the capacitor is probably bad.
