Overview
This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS240LEEA0AAAA gas furnace. The control board is the brain of the furnace — it sequences the inducer motor, igniter, gas valve, and blower, monitors the safety circuit (pressure switch, limits, flame sense), and manages diagnostic LED fault codes. When this board fails, the furnace may not respond to a heat call at all, may run only the blower, may flash error codes, or may behave erratically with no consistent fault. The kit ships with the mounting hardware and instructions needed for a straightforward swap. Replacing a failed board with the exact OEM unit ensures correct ignition timing and full safety-circuit functionality.

Compatibility

Installation Guide
- Safety First — Disconnect power at the furnace switch or breaker and verify zero voltage with a multimeter.
- Access — Remove the furnace control/blower compartment service panel.
- Document — Photograph every wire, plug, and terminal on the existing board before disconnecting anything.
- Remove — Unplug all harness connectors, remove the board mounting screws, and lift out the old board.
- Install — Mount the new board, transfer any jumpers/settings, and reconnect every wire exactly per your photos.
- Test — Restore power, run a full heat cycle, and confirm correct inducer, igniter, gas valve, and blower sequencing with no fault codes.
Signs You Need a Replacement
- No response to a heat call despite good thermostat and power
- Diagnostic LED shows a hard fault or stays off entirely
- Erratic operation — blower-only running, random short-cycling
- Visible burn marks, scorched relays, or corrosion on the board
