Overview
This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS240LFEA0AAAA gas furnace. The board is the brain of the furnace: it sequences the inducer, igniter, gas valve, and blower, monitors safety limits and flame sense, and stores diagnostic fault codes on its LED. A failed board can cause no-heat conditions, blower or inducer that won't start, intermittent operation, or flashing error codes. Supplied as a complete kit for a clean, reliable replacement.
