OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR024000AHAA

This is the factory OEM defrost control board (part# HK32EA001) for the Carrier PH13NR024000AHAA heat pump split system. The defrost board manages the critical defrost cycle — monitoring outdoor coil temperature and initiating a timed reverse-cycle defrost to clear frost and ice buildup from the outdoor unit. When this board fails, common symptoms include the outdoor coil freezing solid, the system getting stuck in heating or cooling mode, the reversing valve failing to switch, or the unit running continuously without completing a proper defrost cycle. Left unaddressed, a failed defrost board can lead to compressor overloading and costly downstream damage.
