The defrost control board monitors outdoor coil conditions and initiates timed defrost cycles to prevent frost and ice accumulation on the evaporator coil. When this board fails, the heat pump will typically remain locked in a continuous frost or ice-over state, fail to enter the defrost cycle at all, or cause the system to short-cycle and lose heating capacity — leaving you without heat on the coldest days.\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 | Factory Authorized Parts by Carrier Corporation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine OEM boards are manufactured to exact Carrier factory tolerances and preserve your unit's warranty.
