ICP Furnace Control Board Kit for RGS213SDAA0AAAA — OEM | Ships Today

Overview

This genuine OEM control board kit (OEM part 1183618) is the integrated furnace control (IFC) that runs the entire heating sequence on your ICP RGS213SDAA0AAAA furnace. It manages the ignition timing, gas valve, inducer and blower relays, safety circuit monitoring, and flame sensing, and it flashes diagnostic fault codes through its onboard LED. Boards fail from power surges, overheating, cracked solder joints, or corroded relays. Typical symptoms include no response on a heat call, the blower or inducer running continuously, intermittent no-heat, or a board that throws error codes and locks out the system.
