Overview
This is the genuine OEM furnace control board kit (part 1183618) for the ICP / Tempstar / Heil RGS091HDCA0AAA gas furnace. The integrated control board is the brain of the furnace: it sequences ignition, monitors flame via the sensor, controls the inducer and blower motors, manages the gas valve, and enforces all safety interlocks (limit, pressure, and flame-proving circuits). When the board fails, the furnace may not start, may short-cycle, may run the blower continuously, or may flash diagnostic fault codes on the onboard LED. This OEM-spec kit restores correct, code-compliant operation and is supplied as a kit for proper fitment to the RGS chassis.
