Overview
This genuine OEM furnace control board kit (part number 1183618, "KIT CONTROL BOARD") is the integrated furnace control (IFC) that manages the entire heating sequence for the ICP/Tempstar/Heil RGS150SFAA0AAAA gas furnace. The board sequences the inducer, hot surface igniter, gas valve, and blower, monitors safety inputs such as the pressure switch and limit, and stores fault codes via its diagnostic LED. When a control board fails — from power surges, corrosion, or burned relays — symptoms range from a completely dead furnace to short cycling, no blower, or random lockouts. Supplied as a kit for a complete, correct replacement.
