Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS150STCB0AAAA gas furnace. The integrated furnace control board is the brain of the unit — it sequences the inducer, energizes the hot surface igniter, opens the gas valve, monitors flame sense and the limit/pressure safety circuit, and times the blower on and off. Boards fail from voltage surges, corrosion, cracked solder joints, and burned relays, producing symptoms ranging from no heat to a blower that won't shut off. This kit includes the board and required mounting hardware for a complete replacement.

Installation Guide
- Safety First — Disconnect electrical power and shut off the gas supply. Verify zero voltage with a multimeter.
- Access — Remove the furnace control/blower compartment panel.
- Document — Photograph every harness, plug, and terminal on the old board before disconnecting — connector positions are critical.
- Remove — Unplug all connectors, remove the mounting screws/standoffs, and take out the old board.
- Install — Mount the new board with the supplied hardware and reconnect every harness exactly per your photos. Match any dip-switch or jumper settings from the old board.
- Test — Restore gas and power, run a full heat cycle, and confirm correct ignition, flame sense, and blower on/off timing.
Signs You Need a Replacement
