OEM Carrier Integrated Furnace Control Board (IFC) for Model PG8UAA060155ABJA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG8UAA060155ABJA gas furnace, supplied under OEM part numbers HK42FZ016 and its direct kit replacement 325878-751. The IFC board is the central nervous system of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor on every call for heat. When the board fails, you'll typically see symptoms such as a complete no-heat lockout, erratic blower behavior, persistent fault codes on the diagnostic LED, or a furnace that starts the ignition sequence but immediately shuts down without ever opening the gas valve.

• OEM Part Numbers: HK42FZ016 (original) | 325878-751 (OEM kit replacement, current) — Note: 325878-751 is the factory-authorized successor to HK42FZ016 and includes adapter wiring harnesses for plug-and-play installation on older wiring configurations.
• Electrical Specs: Input range 98–132 VAC at 60 Hz | Igniter output: 5A at 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1/2 HP, 240 VAC | Inducer motor: 4A (FLA), 8.0A (LRA) at 120 VAC | Compatible with 24 VAC standard thermostat | Built-in diagnostic LED fault codes for rapid troubleshooting
• OEM vs Generic: OEM boards carry factory firmware calibrated for the PG8UAA060155ABJA's exact staging, blower timing, and safety lockout sequences. Generic boards risk mis-timed ignition events and may void equipment warranties. This listing is for the genuine Carrier OEM part only.
• Install Difficulty: 3/5 — Power down the furnace and verify zero voltage before touching any terminals. Tools needed: ¼" and 5/16" nut drivers, needle-nose pliers, phone/camera (photograph all harness connections before removal). The 325878-751 kit includes adapter harnesses if your existing wiring uses the older connector style. Allow 45–60 minutes for a careful first-time install. Electrostatic discharge precautions are recommended — touch grounded metal before handling the board.
