This OEM control board kit, part number 1183618, is the integrated furnace control (IFC) for the ICP RGS213HEAA0AAAA. The board is the brain of the furnace: it sequences the inducer, igniter, gas valve, and blower, monitors safety limits and flame sense, and runs onboard diagnostics through its LED fault codes. When the board fails, the furnace may be completely dead, stick on one stage, blow cold air, or flash error codes that never clear. The kit ships with the necessary mounting hardware for a clean OEM replacement.
