Overview
This OEM ICP control board kit (part number 1183618) is the integrated furnace control (IFC) that serves as the brain of your ICP Tempstar/Heil RGS243SSEA0AAAA gas furnace. It manages the entire heating sequence — inducer operation, igniter timing, gas valve control, flame sensing, blower timing, and safety lockouts — and communicates fault codes through its diagnostic LED. A failed board commonly results from power surges, moisture, cracked solder joints, or burned relay contacts. Symptoms of a bad control board include a completely dead furnace, no response to a thermostat call for heat, blower or inducer that won't start or won't shut off, and erratic or absent diagnostic LED codes.

Installation Guide
- Safety First — Disconnect electrical power at the furnace switch and breaker; verify zero voltage with a multimeter before handling the board.
- Access — Remove the furnace control/blower access panel to expose the existing board.
- Document — Photograph every wire harness and connector position before disconnecting anything.
- Remove — Unplug all harness connectors, remove the mounting screws, and lift out the old board.
- Install — Mount the new board, transfer any required jumpers/settings, and reconnect each harness exactly per your photos.
- Test — Restore power, run a full heat cycle, and confirm proper ignition, blower timing, and a steady diagnostic LED.
Signs You Need a Replacement
