Overview
This genuine ICP control board kit (OEM part 1183618) is the integrated furnace control (IFC) that manages the entire heating sequence in the ICP / Tempstar / Heil RGS120HFBA0AAA gas furnace. The board orchestrates the inducer motor, hot surface igniter, gas valve, and blower timing, monitors safety circuits such as the pressure switch and limit, and provides diagnostic LED fault codes. When the board fails — often from surges, heat stress, or a cracked solder joint — the furnace may not start, may lock out, may short-cycle, or may run the blower continuously. Supplied as a kit for a complete, reliable replacement, this control restores correct ignition sequencing and safety supervision.

- Test — Restore gas and power, run a full heat cycle, and confirm proper ignition, blower timing, and absence of fault codes.
