The defrost control board monitors outdoor coil temperature and ambient conditions, then orchestrates timed defrost cycles to prevent ice buildup on the outdoor unit. When this board fails, the heat pump may run in continuous heating mode while icing over, fail to initiate defrost cycles altogether, cycle the reversing valve erratically, or trigger a system lockout fault — all symptoms that lead to reduced efficiency and potential compressor damage if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control voltage | 5A amperage | Single-phase | Board model CEPL130524-01 \/ CEBD430524-06A | Compatible cross-references: 151922, RT444024F | Replaces Potter \u0026amp; Brumfield relay T9AS2D22-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory-authorized OEM board is manufactured to exact Carrier tolerances and pre-programmed with the correct defrost timing logic for your unit.
