OEM Carrier Defrost Control Board HK32EA007 for Model PH13PR03600GALAA

This is the factory OEM defrost control board for the Carrier PH13PR03600GALAA heat pump. The defrost control board manages and initiates the timed defrost cycle, monitoring the outdoor coil temperature sensor to determine when frost accumulation requires a defrost purge. When this board fails, the outdoor coil will ice over completely, severely degrading heating capacity or causing the system to lock out entirely. Common symptoms include a frozen outdoor unit, continuous or absent defrost cycles, and error codes indicating a defrost fault or pressure trip.

• Specs: OEM Part # HK32EA007 | 1-Phase | 24V control circuit | Timed/demand defrost logic | Factory-matched for Carrier PH13 series heat pumps
• OEM vs Generic: This is a genuine Carrier OEM board with factory-programmed defrost timing intervals and sensor thresholds. Aftermarket boards may use mismatched timing logic, leading to under- or over-defrost conditions that accelerate compressor wear and reduce efficiency.
• Install difficulty: 3/5 — Power down and lock out the unit before beginning. Photograph all wiring harness connections before disconnecting. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, a multimeter to verify 24V control voltage. A qualified HVAC technician is recommended for this repair.
