OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG9MAA060120ABKA

This OEM integrated furnace control board (IFC) is the factory-specified replacement for the Carrier PG9MAA060120ABKA gas furnace. The control board is the central brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor in the correct order every heating cycle. When the board fails, common symptoms include a complete no-heat lockout, the furnace starting and immediately shutting down, erratic blower behavior, or the system failing to call the gas valve after a successful ignition. Diagnostic LED fault codes on the board itself can help pinpoint the exact failure mode before and after replacement.

• OEM vs Generic: This OEM board is programmed with Carrier's exact ignition timing, blower delay profiles, and fault logic for the PG9MAA060120ABKA. Generic aftermarket boards often use generic timing tables that can cause nuisance lockouts, improper blower delays, or voided equipment warranties. OEM is the only safe choice for a safety-critical component like a furnace control board.
• Install Difficulty: 3/5 — Shut off power and gas before starting. The 325878-751 kit includes wiring adapter harnesses for older-style board connectors, making it plug-and-play for most installations. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, phone camera (photograph all wiring before disconnecting). Note the diagnostic LED fault code on the old board before removal. Allow 15–30 minutes for a careful installation.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
