The defrost control board monitors outdoor coil temperature and ambient conditions, initiating timed defrost cycles to melt ice buildup and restore efficient heat transfer. When this board fails, symptoms include a permanently iced-over outdoor coil, a heat pump stuck in defrost mode, failure to switch between heating and cooling, or a system that delivers cold air during heating operation. Left unaddressed, a failed defrost board can cause compressor damage from liquid slugging — making prompt replacement critical.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control voltage | 5A amperage | Single-phase | Board ID: CEPL130524-01 \/ CEBD430524-06A | Direct OEM replacement — no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier Factory Authorized Part matches exact timing intervals, relay ratings, and sensor thresholds.
