OEM Carrier Defrost Control Board HK32EA001 for Model PH10JA04800GABAA

This OEM defrost control board (part number HK32EA001) is the factory-specified replacement for the Carrier PH10JA04800GABAA heat pump. The defrost control board manages the automatic defrost cycle by monitoring run time and outdoor coil temperature, then temporarily reversing refrigerant flow to melt frost buildup from the outdoor coil. When this board fails, common symptoms include the outdoor unit staying locked in a frost-covered state, the heat pump failing to switch between heating and cooling modes, reduced heating efficiency in cold weather, or the system tripping on high-pressure lockout due to a blocked coil.
