The defrost control board manages the automatic defrost cycle by monitoring run time and outdoor coil temperature, then temporarily reversing refrigerant flow to melt frost buildup from the outdoor coil. When this board fails, common symptoms include the outdoor unit staying locked in a frost-covered state, the heat pump failing to switch between heating and cooling modes, reduced heating efficiency in cold weather, or the system tripping on high-pressure lockout due to a blocked coil.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number \u0026amp; Specs:\u003c\/strong\u003e OEM part HK32EA001 | Board model CEPL130524-01 | 24V control voltage | 5A amperage | Single-phase | Replaces cross-references: CEBD430524-06A, 151922\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part — engineered to exact factory tolerances.
