OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR060000AEAA

This is the factory OEM defrost control board for the Carrier PH13NR060000AEAA heat pump. The defrost control board manages the automatic defrost cycle, monitoring outdoor coil temperature and run time to prevent ice buildup on the heat exchanger. When this board fails, common symptoms include a continuously iced outdoor coil, a heat pump stuck in defrost mode, failure to enter or exit defrost at all, or system lockout with no heating output — especially in cold-weather operation.
