The defrost control board monitors outdoor coil temperature and ambient conditions, initiating timed defrost cycles to prevent ice buildup on the outdoor coil. When this board fails, your heat pump may stay locked in cooling mode, fail to reverse into heating, short-cycle erratically, or run continuously without ever triggering a defrost cycle — leaving you with a frozen-over outdoor unit and no heat on the coldest days.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part # HK32EA001 | Board ID: CEPL130524-01 \/ CEBD430524-06A | 24V control voltage | 5A | Single-phase | Compatible relay: Potter \u0026amp; Brumfield T9AS2D22-24\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.
