ICP Furnace Control Board Kit for RGS180LTAA0AAAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) that runs the entire heating sequence on the ICP Tempstar Heil RGS180LTAA0AAAA. The board manages the inducer, ignition timing, gas valve, blower, and safety lockouts, and provides the diagnostic LED fault codes technicians rely on. Power surges, cracked solder joints, failed relays, and burned traces all cause no-heat, intermittent operation, or blower-won't-stop faults. Supplied as a kit with the matching connectors/hardware for a clean swap.
