Overview
The OEM control board kit (part number 1183618) is the integrated furnace control (IFC) that manages your ICP/Tempstar/Heil RGS180SRCA0AAAA furnace. It sequences the inducer, igniter, gas valve, and blower, monitors the safety circuit, and runs the diagnostic LED. A failed board causes no-heat conditions, blower or inducer faults, blank diagnostics, or erratic operation. This genuine replacement kit restores correct, safe ignition sequencing.
