OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG8DAA060115ABJA

This OEM integrated furnace control board (IFC) is the factory-specified replacement for the Carrier PG8DAA060115ABJA packaged gas furnace. The IFC board is the brain of the heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower through every heat call. When it fails, symptoms range from a complete no-heat lockout and repeated ignition attempts to erratic blower behavior, fault LED codes, or a furnace that starts but immediately shuts down. The OEM part number HK42FZ016 has been superseded by the updated kit 325878-751, which ships with wiring adapter harnesses for seamless plug-and-play installation on both legacy and current board configurations.

• Specs: Input: 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, 120 VAC | Gas valve: 1A at 24 VAC | Compatible with 24 VAC standard thermostat | Diagnostic LED fault codes included
• OEM vs Generic: This is a genuine Carrier OEM board factory-tested to exact tolerances for the PG8DAA060115ABJA. Generic aftermarket boards (ICM282-series) can introduce timing drift and may void equipment warranties — OEM is the correct choice for warranty repairs and maximum system longevity.
• Install difficulty: 3/5 — Shut off gas and 120V power at the disconnect before beginning. The 325878-751 kit includes adapter harnesses for older-style connectors. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Discharge any residual voltage and handle the board only by its edges to avoid electrostatic damage.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our stocked warehouse.
