Overview
This OEM control board kit (ICP part 1183618) is the integrated furnace control (IFC) brain of your ICP/Tempstar/Heil RGS102STBA0AAA gas furnace. It sequences the entire heat cycle — energizing the inducer, proving the pressure switch, powering the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on/off delays — while running continuous safety checks. When the board fails you may see a dead furnace with no response to a heat call, erratic short-cycling, a blower that won't shut off, or a flashing diagnostic LED indicating an internal fault. The kit includes the replacement board for a direct swap.
