This genuine OEM control board kit, part number 1183618, is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS180SDAA0AAAA. The board manages the entire heating sequence — inducer start, pressure-switch proving, igniter timing, gas-valve energizing, blower control, and safety lockouts. A failed board is one of the most common causes of a dead or erratically cycling furnace: no response on a heat call, blower running constantly, or repeated lockout flash codes. This kit ships as a complete board assembly for a direct factory replacement.
