Overview
The 1183618 control board kit is the OEM integrated furnace control (IFC) for the ICP Tempstar / Heil RGS240STEA0AAAA gas furnace. This board orchestrates the entire heat cycle — it sequences ignition, monitors the flame sensor and pressure switches, drives the inducer and blower motors, and enforces safety lockouts. A failed board can leave the furnace unable to ignite, short-cycling, locked out, or unresponsive to the thermostat. Common symptoms include the inducer running with no ignition, blinking diagnostic LED fault codes, or no activity on a call for heat. This kit ships as a complete OEM assembly to restore reliable, code-compliant furnace operation.
