Or just take the hole thing to the grainger store

This capacitor (if working right) stores energy.... What precautions should it take when handling this item. I know an automobile unit will put you on the floor.

Ok, will do. Is there a way to bypass inline devices such as relays and such to ensure the motor is not the issue? The motor spins freely so I do not think a bearing is bad.

Answer

Hello

I would start with the start cap if it's humming this is the most likley cause
