OEM Carrier Defrost Control Board HK32EA007 for Model PH14NB03600GABAA

This OEM defrost control board is the factory-specified replacement for the Carrier PH14NB03600GABAA heat pump. The defrost control board manages timed and sensor-triggered defrost cycles, signaling the reversing valve and outdoor fan to clear ice accumulation from the outdoor coil during heating season. When this board fails, you may notice the outdoor unit becoming heavily iced over, defrost cycles that never initiate, or a heat pump that runs continuously without adequate heating output — all signs the board can no longer read sensor inputs or trigger the defrost sequence.
