The IFC board is the brain of your heating system — it sequences every stage of the heating cycle, commanding the inducer motor, hot surface igniter, gas valve, and blower motor in precise order. When this board fails, symptoms include the furnace failing to start, going into hard lockout, the blower running continuously, or the system short-cycling with no heat. Diagnostic LED flash codes on the board itself help pinpoint the exact fault before and after replacement.\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, 120 VAC | Microprocessor-based with onboard LED fault diagnostics | OEM part numbers: \u003cstrong\u003eHK42FZ016\u003c\/strong\u003e \/ \u003cstrong\u003e325878-751\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM board, factory-programmed and tested to exact sequencing tolerances for the PG8UAA066111ABJA.
