Overview
This genuine OEM integrated furnace control board kit (part 1183618) is the brain of the ICP / Tempstar / Heil RGS120STAB0AAA gas furnace. It manages the entire heating sequence — inducer startup, pressure-switch proving, hot surface igniter timing, gas valve energizing, flame sensing, and blower on/off delays — while monitoring safety limits and reporting fault codes through its diagnostic LED. When the board fails, the furnace may short-cycle, fail to ignite, run the blower continuously, or go completely dead. Supplied as a kit for a complete, reliable replacement.
