OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG9MAA060120AAKA

This is the factory OEM integrated furnace control (IFC) board for the Carrier PG9MAA060120AAKA 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 through every heating and cooling cycle. When it fails, symptoms range from a complete no-heat lockout and continuous LED fault codes to erratic blower operation, short-cycling, or a furnace that starts then shuts down mid-cycle. Note: OEM part number HK42FZ016 has been superseded by the updated kit 325878-751, which includes wiring adapter harnesses for seamless plug-and-play installation on older harness configurations.

• Specs: Input: 98–132 VAC @ 60 Hz | Igniter output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat: 5A, 1/2 HP, 240 VAC | Inducer: 4A (FLA), 8.0A (LRA) @ 120 VAC | 24 VAC standard thermostat compatible
• OEM vs Generic: This OEM board ships from Carrier's factory-authorized supply chain with verified firmware and tolerance specs. Aftermarket ICM282-series boards may lack factory diagnostic logic, increasing the risk of nuisance lockouts and shortened component life.
• Install difficulty: 3/5 — Power off and tag out the furnace before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone/camera to photograph all wiring connections before removal. The 325878-751 kit includes adapter harnesses if your existing wiring does not mate directly to the new board's connectors.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
