ICP Furnace Control Board Kit for RGS102STAB0AAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part #1183618) is the integrated furnace control (IFC) brain of the ICP Tempstar Heil RGS102STAB0AAA. It sequences the entire heating cycle — energizing the inducer, proving the pressure switch, firing the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on and off delays. It also runs safety lockouts and flashes diagnostic fault codes. When the board fails, you can see no response on a call for heat, intermittent operation, blower or inducer that won't start, repeated lockouts, or erratic diagnostic LED codes. Replacing the board restores correct ignition sequencing and safety control. The kit ships with mounting hardware for a direct OEM swap.
