If the fan motor fails the compressor will drop out on thermal protection.

Will the fan spin freely when power is removed?
It may only need a capacitor. Match microfarad and voltage.
A 5 mfd 370 volt example...


If you have a dual capacitor it should not be swollen.

"Tip of the Day" Remember to remove power first.
