Is the motor HOT when it shuts off like this ?

Can you spin the wheel several revolutions at this time ?


Have you removed and inspected it ?


Could be motor, run capacitor, fan switch or a wiring problem.



Thanks,
Robert

That sounds like a possible bearing seizing up. If so, motor is overheating and shutting down.


Is the motor getting full 120 volts to the wires going to motor ?


Do you have heat only or heat & a/c ?



Thanks,
Robert

With 120vac getting to motor, it being HOT when it turns off early, wheel being hard to turn and it making sounds, most likely seized bearings .


Will be back in office later this evening if you would like a price quote and ordering info for a new motor.


Is it heat only or heat and a/c unit ?



Thanks,
Robert
