OEM Carrier Defrost & Fan Blower Control Board CESO130076-00 for Model PH3ZNA060000AA

This is the factory OEM defrost and fan blower control board for the Carrier PH3ZNA060000AA heat pump system. Cross-referenced under part numbers CESO130076-00 and HK61EA011, this board is the central command module of your heat pump — continuously monitoring sensors, safety switches, and operating conditions to coordinate defrost cycles, blower staging, and system protection logic. When this board fails, symptoms typically include: the system failing to enter or exit defrost mode, the blower fan running erratically or not at all, unexplained error codes or lockouts, or the unit refusing to heat even when the compressor is running.

• OEM Part Numbers: CESO130076-00 (Control Board) | HK61EA011 (Fan Blower Control Board) — both references covered by this single factory board. Also supersedes kit part 38EY660001.
• OEM vs Generic: This is a genuine OEM Carrier board, manufactured to exact factory specifications for the PH3ZNA060000AA. Generic aftermarket boards frequently use off-spec relays and firmware logic that can cause nuisance lockouts, improper defrost timing, or premature failure — particularly in heat pump applications where defrost sequencing is critical.
• Install Difficulty: 3/5 — Requires isolation of 240V power at the disconnect and breaker panel before opening the control compartment. Photograph all wiring harness connections before removal. Tools needed: Phillips and flathead screwdrivers, 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter for post-install verification. Not recommended for unlicensed DIY in jurisdictions requiring HVAC permits.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our climate-controlled warehouse — order by 3 PM local time for same-day dispatch.
