Overview
This OEM control board kit (part #1183618, KIT CONTROL BOARD) is the integrated furnace control that runs the entire heating sequence on your ICP Tempstar Heil RGS240SEFA0AAAA. The board manages the inducer, igniter, gas valve, blower timing, flame sensing, and all safety interlocks, coordinating each step from thermostat call to ignition to blower-off delay. It also reports fault codes through its diagnostic LED. When a board fails — from voltage surges, age, or moisture — you may see no response to a heat call, the blower running constantly, intermittent lockouts, or flashing error codes. Supplied as a complete kit, this replacement restores correct, safe sequencing and proper diagnostics.
