OEM Carrier Defrost Control Board HK32EA001 for Model PH15NB06000GBAAA

This is the genuine OEM defrost control board (part number HK32EA001), factory-specified for the Carrier PH15NB06000GBAAA heat pump. The defrost control board monitors outdoor coil temperature and elapsed run time to determine when the heat pump must enter a defrost cycle. When the board fails, the outdoor coil will ice over, heat output drops dramatically, and the unit may lock out entirely — leaving you with no heat on the coldest days. Cross-reference part numbers include: CEPL130524-01, CEBD430524-06A, 151922, 1173636, 1177927.

• Part Type: Defrost Timer / Control Board | OEM Part Number: HK32EA001 | Replaces: CEPL130524-01, CEBD430524-06A, 1173636, 1177927
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket copy. OEM boards use factory-matched relay specifications (Potter & Brumfield T9AS2D22-24) and pre-set defrost timing logic calibrated for Carrier compressor staging. Generic boards often exhibit relay chatter and mis-timed defrost exits that can damage the reversing valve over time.
• Install Difficulty: 3/5 — Shut off power at the disconnect and breaker before opening the control panel. Photograph all wiring connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Verify defrost termination thermostat and outdoor coil sensor before replacing the board — a faulty sensor can cause premature board failure.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
