ICP Control Board Kit for RGS210HSEA0AAAA — OEM 1183618 Furnace Board | Ships Today

Overview

This OEM control board kit, ICP part number 1183618, is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS210HSEA0AAAA. The board is the brain of the unit — it sequences the inducer, igniter, gas valve, and blower, monitors safety switches and the flame signal, and flashes diagnostic fault codes through its onboard LED. Boards fail from voltage surges, heat, cracked solder joints, or burned relays, producing symptoms ranging from no response on a call for heat to short cycling, blower running constantly, or repeated ignition lockouts. The kit ships with the board and mounting hardware so you can restore proper sequencing and safety control.
