This is the OEM control board kit (part number 1183618) for the ICP/Tempstar/Heil RGS102LDAA0AAA gas furnace. The integrated furnace control board is the brain of the furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower, monitors the pressure switch and limit/rollout safeties, reads the flame sensor, and runs the diagnostic LED fault codes. When it fails, the furnace may be completely dead, stuck on the blower, short-cycling, or flashing error codes with no heat. The kit includes the board and the mounting/wiring hardware needed for a clean swap. Replacing the board restores correct ignition timing, blower delays, and safety lockout behavior.
