Overview
This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS091SFCA0AAA gas furnace. The board is the brain of the furnace — it manages the ignition sequence, monitors flame, sequences the inducer and blower motors, and runs the system's safety lockout logic. When this board fails the furnace may fail to ignite, short cycle, lock out after several attempts, run the blower continuously, or do nothing at all. Replacing the board with the correct OEM kit restores reliable, code-compliant operation without guesswork.
