The defrost control board governs the timing and initiation of defrost cycles, sending commands to the reversing valve and outdoor fan to shed ice buildup from the coil during heating operation. When this board fails, the heat pump may remain locked in cooling mode, fail to initiate a defrost cycle entirely, or exhibit short-cycling and frost accumulation on the outdoor unit — all of which severely degrade heating efficiency and can lead to compressor damage if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control circuit | Board model CEPL130524-01 | Compatible relay: Potter \u0026amp; Brumfield T9AS2D22-24 | Single-phase | OEM 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.
