This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) brain of the ICP RGS102LRBB0AAA. It sequences the entire heating cycle — energizing the inducer, proving pressure switches, firing the hot surface igniter, opening the gas valve, monitoring flame, and timing blower on/off delays. It also manages safety lockouts and runs the diagnostic LED fault codes. A failed board shows up as intermittent operation, no response to thermostat calls, blower running constantly, or repeated lockouts that no single component swap resolves.
