OEM Carrier Control Board CESO130076-00 / HK660003 for Model PH3GNA060000AA

This is the factory OEM integrated furnace control (IFC) board for the Carrier PH3GNA060000AA packaged heating unit. The control board is the nerve center of your system — it orchestrates the complete sequence of operation, including inducer startup, hot surface igniter timing, gas valve activation, blower motor staging, and all safety circuit monitoring. When this board fails, common symptoms include a system that won't initiate a heat cycle, gets stuck in lockout mode, throws continuous error fault codes, or experiences erratic blower and ignition behavior that no other single component can explain.

• OEM Part Numbers: CESO130076-00 (primary) | HK660003 (cross-reference) — both are factory-original Carrier boards; verify your unit's data plate before ordering.
• OEM vs Generic: This is a genuine OEM Carrier board, manufactured to exact factory specifications. Aftermarket boards often lack proper fault-code calibration and safety-timing precision, risking nuisance lockouts, voided equipment warranties, and potential safety hazards.
• Install Difficulty: 4/5 — Board replacement requires de-energizing and lock-out/tag-out of the unit, careful photograph documentation of all wiring harness connections prior to removal, and post-installation verification of the full ignition sequence. Recommended tools: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Professional installation strongly advised.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.
