OEM Carrier Defrost Control Board HK32EA007 for Model HP13PR03000GAKAA

This is the factory OEM defrost control board (part number HK32EA007) for the Carrier HP13PR03000GAKAA heat pump. The defrost control board monitors outdoor coil temperature and initiates timed defrost cycles to prevent ice buildup on the outdoor unit. When this board fails, you may notice the outdoor coil freezing solid, the system locking out of heating mode, erratic defrost cycling, or the unit running in emergency heat continuously. Replacing it with the correct OEM board restores factory-programmed defrost timing and protects compressor longevity.
