The integrated furnace control (IFC) board is the brain of your heating system: it sequences the inducer motor, hot surface igniter, gas valve, and blower motor through every call for heat. When it fails, the furnace may lockout after ignition attempts, run the inducer but never fire the burners, fail to energize the blower, or display a fault LED code indicating a control board error. Note: \u003cstrong\u003eHK42FZ016 has been superseded by 325878-751\u003c\/strong\u003e, the current OEM kit which includes wiring adapter harnesses for seamless installation on both old- and new-style wiring harnesses.\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 diagnostic LED fault codes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM board is factory-programmed with Carrier-specific ignition timing, blower delay profiles, and safety lockout sequences.
