The IFC board is the brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower in precise timing. When it fails, symptoms range from a complete no-heat lockout and blinking fault LED codes, to erratic blower behavior, failed ignition attempts, or a furnace that powers on but will not fire. Replacing the control board with a factory-matched OEM unit restores all original safety logic and timing parameters.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24 VAC control circuit | Input range: 98–132 VAC at 60 Hz | Igniter output: 5A at 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1\/2 HP, 240 VAC | Inducer motor: 4A at 120 VAC | Diagnostic LED fault codes included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM 325878-751 kit ships with factory wiring adapter harnesses for seamless plug-and-play installation.
