OEM Carrier Defrost Control Board HK32EA007 for Model PH13PR06000GAJAA

This is the genuine OEM Carrier defrost control board (part number HK32EA007), the factory-specified replacement for the Carrier PH13PR06000GAJAA heat pump. The defrost control board monitors outdoor coil temperature and ambient conditions to initiate, manage, and terminate defrost cycles. When this board fails, the outdoor unit may accumulate excessive ice or frost on the coil, lose heating capacity, or short-cycle without completing a proper defrost. In some cases, the unit may fail to enter defrost mode entirely, causing the coil to freeze solid and the system to shut down on a protection lockout.
