The defrost control board governs when and how long the unit enters its defrost cycle — periodically reversing refrigerant flow to melt ice accumulation off the outdoor coil. When this board fails, the outdoor coil builds frost unchecked, heat output collapses, and the unit may lock out entirely. Common failure symptoms include: persistent icing on the outdoor coil, the heat pump running in cooling mode during heating season, or a complete loss of heating with no fault recovery.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part # HK32EA001 | Board ID: CEPL130524-01 \/ CEBD430524-06A | Voltage: 24V | Phase: 1-Phase | 5A | Factory-matched relay and timer components including Potter \u0026amp; Brumfield T9AS2D22-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine Carrier OEM boards are manufactured to exact factory tolerances and pre-tested for compatibility with the PH15NB04800GBAAA control circuit.
