OEM Carrier Integrated Furnace Control Board HK42FZ016 (325878-751) for Model PG9MAA060080ABKA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG9MAA060080ABKA gas furnace, carrying primary part number HK42FZ016 and updated kit number 325878-751. The IFC board is the brain of your furnace — it sequences every heating cycle from inducer startup through hot-surface ignition, gas valve operation, and blower shutdown. When it fails, symptoms typically include a furnace that won't start, one that locks out after repeated ignition attempts, erratic blower behavior, or a completely unresponsive system with no LED diagnostic activity. Diagnosing a faulty board is straightforward: a functioning board will flash a fault code on its diagnostic LED; a dead board will show nothing at all.

• Specs: Input: 98–132 VAC at 60 Hz | Ignitor output: 5A at 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1/2 HP, 240 VAC | Inducer motor: 4A / FLA-8.0 LRA at 120 VAC | Compatible with 24 VAC standard thermostat | Microprocessor-based with diagnostic LED fault codes
• OEM vs Generic: This OEM board is factory-programmed with Carrier's exact sequencing logic, ignition timing, and 100% gas shutoff protocols — features that generic aftermarket boards frequently mis-calibrate, risking nuisance lockouts or unsafe ignition delays. The 325878-751 kit version includes wiring harness adapters for seamless installation on earlier-harness units.
• Install difficulty: 3/5 — Shut off power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone/camera to photograph all wiring before disconnecting. The 325878-751 kit includes adapter harnesses that simplify plug-in on legacy wiring configurations. Always attach the included fault-code label to the furnace door after installation.
• Warranty: 1-year OEM manufacturer warranty. In-stock — ships same business day from our warehouse.
