OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR04200GAEAA

This is the genuine OEM defrost control board (part number HK32EA001), factory-specified for the Carrier PH13NR04200GAEAA heat pump. The defrost control board monitors outdoor coil conditions and initiates timed defrost cycles to melt frost buildup from the evaporator coil — a critical function in heat pump operation during cold weather. When this board fails, you'll typically see continuous frost or ice accumulation on the outdoor unit, the system failing to enter defrost mode, reduced heating efficiency, or the unit locking out entirely. Cross-reference part numbers include: CEPL130524-01, CEBD430524-06A, 1173636, and 1177927.

• Specs: OEM Defrost Control Board | Part No. HK32EA001 | Compatible successor: HK32EA007 | 24V control circuit | Selectable defrost intervals (30/60/90 min) | Manufacturer: Carrier / Factory Authorized Parts
• OEM vs Generic: This is the genuine Carrier factory part — not an aftermarket substitute. OEM boards are calibrated to factory defrost timing tolerances. Generic boards often use lower-grade relays and lack original connector quality, risking premature failure and potential compressor damage from prolonged icing.
• Install difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring before removal. Note defrost time selector position before swapping boards. If upgrading from HK32EA001 to HK32EA007, set defrost time to 60 minutes.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
