This is the OEM integrated furnace control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS240SFEA0AAAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors the flame and limit switches, and runs the built-in safety lockouts and diagnostic LED fault codes. When this board fails, the furnace typically will not respond to a thermostat call, gets stuck in a single stage of the ignition sequence, or short-cycles. Because it ships as a complete kit, it includes the mounting hardware and wiring connectors needed for a clean replacement.
