ICP Furnace Control Board Kit for RGS210SREA0AAAA – OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit, ICP part number 1183618, is the integrated furnace control (IFC) that orchestrates the entire heating and blower sequence. It manages the call for heat, inducer and pressure-switch proving, igniter and gas-valve timing, flame sensing, and blower on/off delays, while monitoring safety limits and reporting fault codes via its diagnostic LED. When the board fails, the furnace may fail to start, lock out, short-cycle, or run the blower continuously. Because the board ties every component together, it is a frequent diagnosis when multiple symptoms appear at once. This kit includes the board for a direct OEM replacement.
