OEM Carrier Defrost Control Board HK32EA001 for Model PH10JA024000ADAA

This is the factory OEM defrost control board (part number HK32EA001) for the Carrier PH10JA024000ADAA heat pump. The defrost control board manages the timed defrost cycle that prevents ice buildup on the outdoor coil during heating operation. It monitors outdoor temperature and coil conditions, then triggers the reversing valve and engages defrost mode when needed. When this board fails, common symptoms include a continuously iced-over outdoor coil, a heat pump that blows cold air in heating mode, a unit that never initiates or never terminates a defrost cycle, or erratic reversing valve behavior that prevents proper mode switching between heating and cooling.
