The defrost control board manages and initiates timed defrost cycles, monitoring outdoor coil conditions and signaling the reversing valve and defrost relay to shed ice buildup from the outdoor unit. When this board fails, you'll typically see the outdoor coil frozen solid, the unit running continuously in cooling mode during winter, or the heat pump failing to produce adequate heat — all signs that the defrost cycle is no longer being triggered on schedule.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control voltage | 1-phase | 5A | Board dimensions approx. 6\" × 4\" | Cross-references: CEPL130524-01, CEBD430524-06A, 151922 | Factory Authorized Parts (FAP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine Carrier OEM boards are built to exact factory tolerances for timing intervals, relay ratings, and connector pinouts.
