Overview
This genuine OEM control board kit (OEM #1183618) is the integrated furnace control (IFC) — the brain of the ICP / Tempstar / Heil RGS090SFAB0AAA gas furnace. It sequences and supervises every heating cycle: it powers the inducer, checks the pressure switch, energizes the hot surface igniter, opens the gas valve, monitors flame, and times the blower on and off. The kit ships with the mounting and connection hardware needed for a complete swap. When the board fails you may see a furnace that's completely dead, blows cold air, won't ignite, runs the blower constantly, or flashes diagnostic fault codes. Replacing it with the correct OEM kit restores full, code-compliant control of the heating sequence.
