Overview
The 1183618 Control Board Kit is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS150HDCB0AAAA gas furnace. This circuit board is the brain of the furnace — it sequences the ignition cycle, manages the inducer and blower relays, monitors safety limits and flame feedback, and runs onboard diagnostics. When the board fails the furnace typically will not start, will lock out on ignition faults, blows the onboard fuse, or runs the blower continuously. A flashing diagnostic LED with no heat call response is a classic symptom of a failed control board.
