Overview
Genuine OEM integrated furnace control board kit (part 1183618) for the ICP / Tempstar / Heil RGS150HSCB0AAAA packaged gas/electric unit. The control board is the brain of the heating system — it sequences the inducer, hot surface igniter, gas valve, and blower, monitors the safety circuit (limits, pressure switch, flame sense), and manages timing and diagnostics. When it fails, the unit may be completely dead, stuck in a single mode, short-cycling, or flashing fault codes with no actual component failure. This factory kit includes the correct board revision and mounting hardware for a clean, reliable replacement.
