OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR06000GADAA

This is the factory OEM defrost control board for the Carrier PH13NR06000GADAA heat pump. The defrost control board continuously monitors outdoor coil temperature and initiates timed defrost cycles to prevent frost accumulation on the evaporator coil. When this board fails, the outdoor coil will ice over rapidly, causing the system to lose heating capacity, trip high-pressure safeties, or lock out entirely. Common failure symptoms include: the unit running in a perpetual defrost cycle, the heat pump failing to switch from cooling to heating mode, or the system short-cycling due to uncontrolled frost buildup.

• OEM Part Number: HK32EA001 | Also referenced as CEPL130524-01, CEBD420524-04A, CEBD430524-04B, 1173636, 1177927 | 24V control circuit | Single-phase
• OEM vs Generic: This is a genuine Carrier OEM board built to exact factory tolerance. Aftermarket defrost boards frequently mistime defrost intervals, leading to repeat icing events, compressor stress, and callbacks — a false economy on a critical safety-linked component.
• Install Difficulty: 3/5 — Requires disconnecting low-voltage control wiring harness and mounting screws inside the outdoor unit. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, insulated screwdriver. Always shut off power at the disconnect before opening the control panel. Photograph all wiring connections before removal. Note defrost time selection DIP switch settings on old board before swapping.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our warehouse when ordered before cutoff.
