Overview
This genuine OEM control board kit (part #1183618) is the integrated furnace control (IFC) that runs every safety and sequencing function in your ICP, Heil, or Tempstar RGS091SECB0AAA gas furnace. It manages the inducer, hot surface igniter, gas valve timing, blower fan-on/fan-off delays, flame sensing, and the diagnostic LED fault codes. When the board fails, symptoms range from a completely dead furnace to erratic blower operation, short cycling, or repeated ignition lockouts. Because the IFC ties every component together, a failing board is often misdiagnosed as an igniter, gas valve, or blower problem — this kit restores the furnace to factory control logic.
