OEM Carrier Defrost Control Board HK32EA001 for Model PH4RNG060000BAAA

This is the genuine OEM defrost control board (part number HK32EA001), factory-specified for the Carrier PH4RNG060000BAAA heat pump. The defrost control board monitors operating time and outdoor coil temperature to determine when to initiate a defrost cycle. When this board fails, the outdoor coil can ice over completely, causing the unit to lose heating capacity, trip high-pressure safeties, or run continuously without ever entering defrost mode. Replacing it with the correct OEM board restores precise defrost timing and protects the compressor from sustained refrigerant slugging.

• Part Number: HK32EA001 | Also references CEPL130524-01, CEBD430524-06A, 1173636, 1177927 | Factory Authorized Carrier Replacement Components Division part
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards maintain factory-calibrated defrost intervals (30/60/90 min selectable), correct relay switching logic, and exact connector pinout. Generic boards often use wider-tolerance timing circuits that can cause under- or over-defrosting, accelerating coil damage.
• Install Difficulty: 3/5 — Disconnect power at the breaker before opening the control panel. Photograph all wiring harness connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, a phone camera. Verify defrost time jumper/dip switch setting matches your application after installation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our stocked warehouse.
