The defrost board manages the timing and logic of defrost cycles, periodically reversing the refrigerant circuit to melt frost accumulation off the outdoor coil. When it fails, symptoms include continuous or absent defrost operation, heavy ice buildup on the outdoor unit, loss of heating capacity, or a system that locks out entirely during cold weather operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Operating voltage: 18–30 VAC | Defrost duration: 10 minutes maximum | Selectable time intervals: 30 \/ 60 \/ 90 \/ 120 minutes | Board cross-references: CEBD430433-08A, CEPL130433-01, CESO130076-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM board is factory-programmed to Carrier's exact defrost timing parameters for the PH3GEAA36000AA.
