OEM Carrier Integrated Furnace Control Board HK42FZ016 for Model PG8DAA048095ABJA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG8DAA048095ABJA gas furnace, sold under OEM part numbers HK42FZ016 and its superseding kit number 325878-751. The IFC board is the brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower in precise timed steps on every heat call. When it fails, symptoms include a hard lockout with no ignition attempt, erratic blower operation, a furnace that starts and immediately shuts down, or a completely unresponsive unit with no LED activity. The onboard diagnostic LED flash codes are your first tool for isolating the fault before condemning the board.

• OEM vs Generic: The OEM board is programmed with Carrier's exact ignition-timing and safety-lockout logic for the PG8DAA048095ABJA. Generic ICM282-series aftermarket boards use approximated firmware that may trigger nuisance lockouts or fail AHJ inspections on permitted repairs. For a safety-critical component controlling gas flow and ignition, OEM is strongly recommended.
• Install Difficulty: 3/5 — Requires safely disconnecting 120V line power and 24V control wiring. Photograph all connector positions before removal. If installing the 325878-751 kit on an older unit, use the included wiring adapter harnesses. Tools needed: Phillips screwdriver, 1/4" nut driver, needle-nose pliers, smartphone for wiring photos. Always verify flash codes on the old board before replacement to confirm the board — not a pressure switch or flame sensor — is the root cause.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
