ICP Furnace Control Board Kit for RGS102HFBB0AAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part 1183618) is the integrated furnace control (IFC) that manages the entire heating sequence on the ICP/Tempstar/Heil RGS102HFBB0AAA gas furnace. The board sequences the inducer motor, hot surface igniter, gas valve, and blower; monitors safety inputs such as the pressure switch, limit switch, and flame sensor; and runs diagnostic LED fault codes. When the control board fails, the furnace may show no response on a heat call, blow cold air, short-cycle, or flash error codes, and accessory loads may stop switching entirely. This complete kit includes the board and mounting hardware for a direct OEM replacement.
