OEM Carrier Defrost Control Board HK32EA007 for Model PH14NB04800GAAAA

This is the factory OEM replacement defrost control board for the Carrier PH14NB04800GAAAA heat pump. The defrost control board manages the timing and sequencing of the defrost cycle, sending commands to the reversing valve, outdoor fan motor, and auxiliary heat strips to clear frost accumulation from the outdoor coil. When this board fails, the heat pump may exhibit continuous ice buildup on the outdoor unit, failure to initiate or exit defrost mode, nuisance lockouts, or a complete loss of heating capacity in cold weather conditions.
