The IFC board is the central nervous system of your furnace — it sequences ignition, monitors flame, controls the inducer and blower motors, manages the gas valve, and provides diagnostic LED fault codes. When this board fails, symptoms range from complete no-heat lockout and erratic blower operation to nuisance shutdowns, error codes, and failure to sequence through the ignition trial.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 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 FLA \/ 8.0A LRA at 120 VAC | Compatible with 24 VAC standard thermostat | Diagnostic LED fault code indicator included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This OEM board is factory-programmed with Carrier's exact sequencing timing, brownout protection thresholds, and ignition retry logic.
