    York diamond 80 fan won't come on.
    York diamond 80 fan won't come on. Changed capacitor. Still will not come on. Fan turns free. Can make it come on by jumping wire from power supply to door switch to open terminal on board. Suspect the heat/cool relay on the control board. Any experience or advise?
