OEM Carrier Defrost Control Board HK32EA001 for Model PH15NA06000GBAAA

This is the factory OEM defrost control board (part number HK32EA001) for the Carrier PH15NA06000GBAAA heat pump. The defrost control board governs the timed defrost cycle that periodically reverses the refrigerant flow to melt frost accumulation off the outdoor coil. When this board fails, you'll typically see continuous frost or ice buildup on the outdoor unit, the system stuck in heating or cooling mode, the reversing valve failing to switch correctly, or the unit short-cycling without completing a defrost event. Left unaddressed, a failed defrost board accelerates compressor damage and dramatically reduces efficiency.
