I just had the same problem. I replaced the motor with no luck. It turned out to be a bad capacitor. If it is a dual capacitor, three prongs on top, it also starts the compressor. It is recommended to replace the capacitor anytime you replace a motor. I would try replacing the capacitor first. It is a lot cheaper that a new motor. If that does not fix the problem then you can get a motor. No harm, no foul. The slow start of the motor is a common symptom of a bad capacitor. The motor is not getting enough voltage. The capacitor increases the voltage like a transformer. It will boost it to almost 400 volts, depending on your unit.

I would replace the contactor if you are getting 24 volts to the contactor and it isn't engaging therefore the magneto on the contactor is out and the contactor will need replacement. If you don't have 24 volts at the contactor then the transformer that sends the 24 volts is bad and will need replacing

Something,is drawing too many amps,most likely the compressor.

Hello, if you are getting 24 volts at the contactor and it doesnot pull in then the Contactor is bad and must be replaced.

Hello, are u recieving 24 volts at the contactor coil terminals where the thermostat wires attach? The contactor will close when it gets 24 volts from the indoor control board on a call for cooling
Yes, 24 volts is present. The contactor points look fine and are not pitted so I thought it still functions. Do you think it could be the winding/transformer on the contactor is faulty? A new Honeywell contactor is app. $30 so it's worth a try before calling in a tech. Thanks!
Without power applied to the coil use your ohm meter to read resistance of the coil. If you read OL the coil is bad
OK. I'll take a reading in the a.m. and report back. Many thanks!
