Overview
This OEM control board kit (part #1183618) is the integrated furnace control (IFC) that manages every ignition sequence on your ICP / Tempstar / Heil RGS090STAA0AAA gas furnace. The board sequences the inducer motor, igniter, gas valve, and blower; reads the flame sensor and pressure switch; and runs the safety lockout logic. When it fails you may see no response on a call for heat, the inducer running but no ignition, the blower running continuously, erratic short-cycling, or an LED flashing a hard-lockout fault code. A cracked solder joint, a failed relay, or surge damage on this board can mimic almost any other furnace fault — making it the part to verify when symptoms don't add up.
