Motor turns freely without belts. But it still hums.
I checked terminals...black ohms to orange, white, and yellow; brown to red. No ohm to case.
I see the centrifugal switch but can't tell for sure I think it is engaged and not locked out to run. Where is the capacitor for this motor..internal?? What about the thermal cutout, would it cause a hum or would it be off or on??
Thanks for your help! This unit is old over 30 yrs?? I don't know if it is worth reworking...belts, hose etc!
