The defrost control board manages the timing and execution of the defrost cycle — periodically reversing refrigerant flow to melt frost accumulation off the outdoor coil. When this board fails, the outdoor coil ices over, heat output drops dramatically, and the system may enter a safety lockout. You may also notice the unit running continuously in heating mode without ever entering a defrost cycle, or conversely, defrosting too frequently and short-cycling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control circuit | OEM part number HK32EA001 | Cross-references: CEPL130524-01, CEBD430524-06A | Compatible board dimensions approximately 6\" × 4\" | Single-phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part.
