Payne PY2PNB060090AA Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost cycle which helps to rid your unit of frost that can build up. It looks to a sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
