The IFC board is the brain of your furnace — it sequences the inducer motor, igniter, gas valve, and blower in a precise order on every call for heat. When it fails, symptoms range from a complete no-heat lockout and error code flashing to erratic short-cycling, a blower that runs continuously, or a furnace that stages through ignition but shuts down unexpectedly. Before replacing the board, verify your flame sensor, igniter, and pressure switch are functioning correctly, as a faulty downstream component can mimic a failed board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK42FZ016 (board only) | 325878-751 (Integrated Furnace Control Board Kit — includes wiring adapter harnesses for legacy-to-modern board upgrades)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized board, manufactured to exact firmware and relay specifications.
