This OEM control board kit, ICP part number 1183618, is the integrated furnace control (IFC) that manages the entire heating sequence on your ICP, Heil, or Tempstar RGS213HDAA0AAAA gas furnace. The board orchestrates the inducer, ignition, gas valve, and blower timing while monitoring safety inputs such as the limit switch, pressure switch, and flame sensor. It is the brain of the furnace — when it fails, you may see no response to a heat call, a furnace stuck in lockout, blower or inducer that won't run, or erratic LED diagnostic fault codes. Supplied as a kit for a complete, reliable replacement.
