The IFC is the brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower in precise order on every call for heat. When it fails, symptoms typically include a hard lockout with no ignition attempt, erratic blower behavior, fault codes on the LED diagnostic display, or a furnace that runs briefly then shuts down and won't restart. Before replacing the board, always verify 24V at the transformer secondary and rule out tripped pressure switches or a faulty flame sensor — these are far more common root causes.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK42FZ016 (Integrated Furnace Control Board) | 325878-751 (Integrated Furnace Control Board Kit — includes wiring adapter harnesses for legacy board swaps)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory board with exact firmware, relay ratings, and terminal layout.
