Overview
This is a genuine OEM integrated furnace control board kit (Part No. 1183618) for the ICP / Tempstar / Heil RGS102LEAA0AAA gas furnace. The control board is the brain of the furnace: it sequences the inducer motor, hot surface igniter, gas valve, and blower while continuously monitoring the pressure switch, limit switches, and flame sensor for safe operation. It also drives the diagnostic LED that flashes fault codes. Control boards fail from heat stress, power surges, corroded relays, and cracked solder joints — symptoms range from a completely dead furnace to intermittent no-heat, blower problems, or repeating lockouts. This kit includes the board and the hardware needed for a direct replacement.

Installation Guide
- Safety First — Turn off the furnace at the service switch and breaker, close the gas valve, and verify zero voltage at the board with a multimeter.
- Access — Remove the furnace control-compartment door.
- Document — Photograph every harness connector and terminal on the old board before unplugging anything.
- Remove — Disconnect all plugs and wires, remove the mounting screws, and lift out the failed board.
- Install — Mount the new board and transfer each connector to the matching position per your photos.
- Test — Restore gas and power and run a full heat cycle, watching the diagnostic LED for a normal run signal.
Signs You Need a Replacement
