The defrost control board monitors outdoor coil conditions and governs the defrost cycle — sensing when frost has accumulated on the evaporator coil and initiating a timed defrost sequence to clear it. When this board fails, symptoms include persistent ice buildup on the outdoor coil, the unit never entering defrost mode, reduced heating efficiency in cold weather, or a full system lockout. Before replacing, verify the defrost thermostat and defrost sensor are functioning correctly; if both check out, the board is the likely culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e HK32EA001 | Also cross-references: CEPL130524-01, CEBD430524-06A, 1173636, 1177927\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized board.
