OEM Carrier Integrated Furnace Control Board HK42FZ016 for Model PG8DAA036095ACJA

This is the OEM factory-specified Integrated Furnace Control (IFC) Board for the Carrier PG8DAA036095ACJA packaged gas unit. Also sold as kit part number 325878-751, this board is the nerve center of your furnace — it sequences the inducer, igniter, gas valve, blower motor, and flame sensor through every heating cycle. When it fails, symptoms include intermittent lockouts, failure to initiate ignition, blower running continuously, or a completely unresponsive system with no fault codes displayed.

• Specs: OEM Part Numbers: HK42FZ016 / 325878-751 | 24V control circuit | Integrated diagnostics with fault code LED | Designed for single-stage gas heat applications
• OEM vs Generic: This is a genuine Carrier OEM board with factory-programmed timing sequences and diagnostic logic. Aftermarket boards may have incompatible timing delays for inducer pre-purge, igniter warm-up, and flame proving — causing nuisance lockouts or unsafe operation. OEM is strongly recommended for control boards.
• Install Difficulty: 3/5 — Photograph all wiring harness connections before disconnecting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone/camera for documentation. Important: Discharge any residual power and confirm 24V transformer output before condemning the board. Reference the wiring diagram printed inside the unit door panel.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
