OEM Carrier Defrost Control Board HK32EA001 for Model PH15NA02400GBAAA

This is the genuine OEM Carrier defrost control board (part number HK32EA001), the factory-specified replacement for the Carrier PH15NA02400GBAAA heat pump. The defrost control board monitors outdoor coil conditions and initiates timed defrost cycles to prevent frost and ice accumulation on the heat exchanger. When this board fails, you'll typically see a unit locked in continuous frost buildup, an outdoor coil completely iced over, or a heat pump that never enters the defrost cycle — all of which severely reduce heating efficiency and can cause compressor damage if left unaddressed.

• Specs: OEM Part # HK32EA001 | Cross-references: CEPL130524-01, CEBD430524-06A, 1173636, 1177927 | 24V control circuit | Adjustable defrost timing intervals | Factory-matched for Carrier PH15NA series heat pumps
• OEM vs Generic: This is a genuine Carrier factory part — not an aftermarket copy. OEM boards are manufactured to exact tolerance and firmware specifications. Aftermarket boards may use off-spec timing logic that causes premature or missed defrost cycles, accelerating compressor wear and voiding system warranties.
• Install difficulty: 3/5 — Disconnect power at the breaker before starting. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter, and camera phone to photograph wiring before disconnecting. Note the defrost time selection jumper position on the old board and replicate it on the new board before powering up.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
