OEM Carrier Defrost Control Board HK32EA001 for Model PH4ANG030000BDAA

This OEM defrost control board is the factory-specified replacement for the Carrier PH4ANG030000BDAA heat pump. The defrost control board manages the system's automatic defrost cycle, monitoring outdoor coil temperature and run time to prevent ice buildup on the coil. When this board fails, common symptoms include the unit remaining stuck in defrost mode, failing to initiate defrost at all, or losing heat output entirely due to a fully iced-over outdoor coil.
