OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR04200GAFAA

This is the genuine OEM Carrier defrost control board (part number HK32EA001), factory-specified for the Carrier PH13NR04200GAFAA heat pump. The defrost control board monitors outdoor coil temperature and timed defrost cycles, signaling the reversing valve and outdoor fan to initiate and terminate defrost when ice accumulates on the coil. When this board fails, common symptoms include the outdoor unit freezing solid, the system failing to switch between heating and cooling modes, short-cycling, or a complete loss of heating performance in cold weather.
