The IFC board is the brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor on every call for heat. When it fails, symptoms range from a complete no-heat lockout and error code flashes on the diagnostic LED, to erratic blower behavior, ignition failure after 3 tries, or a furnace that runs briefly then shuts down hard. Do not replace this board without first ruling out a failed flame sensor, pressure switch, or inducer — the board is downstream of all of them.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK42FZ016 (original) | 325878-751 (current kit with adapter harnesses) | Cross-ref: CEPL1311012-01, CEBD431012-01A, ICM282, 1012-940-M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 98–132 VAC @ 60 Hz | Ignitor output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat: 5A, 1\/2 HP, 240 VAC | Inducer motor: 4A FLA \/ 8.0 LRA @ 120 VAC | Gas valve: 24 VAC standard | Diagnostic LED fault codes included | Reverse polarity \u0026amp; brownout protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM 325878-751 kit ships with factory-matched adapter harnesses for plug-and-play installation — no splicing.
