The defrost control board manages and times the system's defrost cycles, receiving signals from outdoor coil sensors and the thermostat to determine when the unit must enter defrost mode to clear ice buildup from the outdoor coil. When this board fails, the heat pump will remain stuck in a frost-covered state, unable to transfer heat efficiently — leading to reduced heating output, continuous icing of the outdoor coil, system lockout faults, or the unit short-cycling without completing a proper defrost cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control voltage | Board model CEPL130524-01 | Cross-references: 151922, CEBD430524-06A | Single-phase | Dimensions approx. 6\" × 4\" | Direct drop-in OEM replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part (FAP), manufactured to exact factory tolerances.
