I have a Goodman package unit GPC1436H41 6 years old Blower Motor won't start. Had power shortage, but unit was turned off at the thermostat. When I turned it on compressor and condenser fan came on but no fan with thermostat on "auto" or "on". Run capacitor is 1 year old and looks pristine. Blower wheel turns freely. What else can I check for diagnosis. Any advice will be appreciated.
