Running into a problem with a heat pump. Just over a year old Payne heat pump with an 11 year old Bryant air handler. Heat pump was sticking in defrost so I replaced the sensor and defrost board. System still wanting to run emergency heat whenever it calls for heat and only activates heat from the heat pump intermittently. Could I be looking at a bad thermostat or interface on the blower?
