Overview
This OEM Integrated Furnace Control (IFC) board kit, part number 1183618, is the electronic brain of your ICP/Heil/Tempstar RGS244HFEA0AAAA gas furnace. It manages the entire heating sequence — inducer startup, hot-surface ignition, gas valve timing, blower on/off delays, and continuous flame-sense monitoring — while running diagnostic safety checks on every cycle. When this board fails, the furnace typically will not start, locks out after a few ignition attempts, or short-cycles. A failed IFC commonly shows up as a furnace that hums but never lights, a blower that runs continuously, or an LED flashing a fault code. Operating on standard 24V control power, this factory board ships pre-flashed with the correct firmware for this model so the ignition and timing parameters match your furnace exactly.

Compatibility
Engineered as a direct OEM replacement for the ICP/Heil/Tempstar/Comfortmaker RGS244HFEA0AAAA gas furnace. Always match the original part number on your existing board before ordering, as IFC boards are firmware-specific.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the furnace blower-compartment service panel.
- Document — Photograph every wire and connector on the board before disconnecting anything.
- Remove — Unplug the molded harnesses, release the mounting screws/standoffs, and lift out the old board.
- Install — Mount the new board on the same standoffs and reconnect each harness exactly per your photo.
- Test — Restore power and run a full heat cycle; confirm clean ignition, proper blower delay, and no fault codes on the diagnostic LED.
Signs You Need a Replacement
- Furnace will not ignite or locks out after repeated ignition attempts
- Blower runs continuously or fails to start after ignition
- Diagnostic LED flashing a hard-lockout or control-fault code
- Visible burnt traces, scorched relays, or corrosion on the board
