OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG9MAA048060AAKA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG9MAA048060AAKA single-stage gas furnace. The IFC board is the brain of the entire heating system — it sequences the inducer, hot surface igniter, gas valve, and blower motor on every call for heat. When it fails, symptoms range from a complete no-heat lockout and continuous diagnostic LED fault codes to erratic blower behavior, ignition attempts that never fire, or a furnace that powers on but shuts down immediately. Note: OEM part HK42FZ016 has been superseded by the current kit part number 325878-751, which includes wiring adapter harnesses for seamless installation on both older and newer board configurations.

• Specs: 24 VAC control circuit | Input range 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 thermostats | Onboard diagnostic LED flash codes
• OEM vs Generic: This is the genuine Carrier factory board with proprietary sequencing firmware matched to the PG9MAA platform. Aftermarket ICM282-series boards replicate basic functions but lack factory-validated timing parameters — deviations can trigger nuisance lockouts or reduce heat exchanger life. OEM is always the recommended choice for a furnace that handles heat exchanger stress cycles daily.
• Install difficulty: 3/5 — Shut off gas supply and 120V power at the disconnect before starting. The 325878-751 kit includes adapter harness pigtails to bridge any connector differences from the legacy HK42FZ016 board. Tools needed: #2 Phillips screwdriver, 1/4" and 5/16" nut drivers, needle-nose pliers, smartphone (photograph all wiring before disconnecting). Label every wire or use the included harness diagram. Always clear fault codes and run a complete heat cycle to verify operation before closing the cabinet.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
