OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR060000ADAA

This is the genuine OEM defrost control board (part number HK32EA001), factory-specified for the Carrier PH13NR060000ADAA heat pump. The defrost control board monitors outdoor coil conditions and initiates timed defrost cycles to prevent frost and ice buildup on the evaporator coil. When this board fails, the heat pump may run continuously in defrost, never enter defrost at all, or lock out entirely — leaving you with a coil encased in ice and no heating output. Cross-reference part numbers include CEPL130524-01, CEBD430524-06A, 1173636, and 1177927.

• Specs: 24V control circuit | Adjustable defrost initiation timing (30 / 60 / 90 minute selectable) | Compatible with Potter & Brumfield T9AS2D22-24 relay | OEM board CEPL130524-01 / CEBD430524-06A
• OEM vs Generic: This OEM board is manufactured to Carrier's exact factory specifications, ensuring precise defrost timing and reliable reversing valve control. Aftermarket boards often use looser tolerances that can cause premature re-icing or nuisance lockouts.
• Install difficulty: 3/5 — Disconnect power at the breaker and wait for capacitors to discharge before handling. Photograph all wiring harness connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Note defrost time selector jumper position before swapping boards.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
