OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG9MAA060140AAKA

This is the factory-specified OEM Integrated Furnace Control (IFC) board for the Carrier PG9MAA060140AAKA gas furnace. The IFC board is the brain of your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor on every call for heat. When this board fails, symptoms range from a complete no-heat lockout and flashing fault LED codes to erratic blower behavior, ignition attempts with no gas valve opening, or a furnace that starts then immediately shuts down. OEM part HK42FZ016 has been superseded by the updated 325878-751 Integrated Furnace Control Board Kit, which includes plug-in adapter harnesses for seamless drop-in installation on all compatible models.

• Specs: Input voltage 98–132 VAC @ 60 Hz | Ignitor output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1/2 HP, 240 VAC | Inducer motor: 4A, FLA-8.0 LRA @ 120 VAC | Gas valve: 1A @ 24 VAC | Compatible with 24 VAC standard thermostat
• OEM vs Generic: This OEM board uses factory-matched firmware and load ratings. Third-party boards may carry ±10% tolerance deviations on blower and inducer relay ratings, risking nuisance lockouts or premature component failure. The OEM 325878-751 kit also includes wiring adapter harnesses — generic boards typically do not.
• Install difficulty: 3/5 — Disconnect power and gas before starting. Photograph all wiring connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone camera for reference photos. The 325878-751 kit includes adapter harnesses that simplify installation on older wiring harnesses. Always clear fault codes and run a full heating cycle after installation to verify operation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
