Overview
This is the genuine OEM Integrated Furnace Control (IFC) board kit, part number 1183618, for the ICP / Tempstar / Heil RGS101STCB0AAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, monitors the flame sensor and pressure switches, sequences the inducer and blower motors, and runs the built-in safety lockouts. When this board fails, the furnace will typically not respond to a call for heat, will short-cycle, lock out after a few ignition attempts, or run the blower continuously. A flashing diagnostic LED with no heat output is the classic symptom of a failed control board. This kit ships as a complete assembly so it installs cleanly as a direct OEM replacement.
