The defrost control board monitors outdoor coil temperature and run-time intervals to initiate and terminate defrost cycles automatically. When this board fails, common symptoms include the outdoor unit icing over completely, the system staying locked in defrost mode, the reversing valve failing to switch between heating and cooling, or the unit short-cycling without ever completing a defrost cycle. Left unaddressed, a failed defrost board can cause compressor damage due to refrigerant flooding from excessive ice buildup.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control voltage | 5A amperage | 1-phase | Board ID: CEPL130524-01 \/ CEBD430524-06A | Includes integrated defrost timer and relay logic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part — not an aftermarket clone.
