Overview
This is the genuine OEM integrated furnace control board kit (part #1183618) for the ICP / Tempstar / Heil RGS150HFAA0AAAA. The control board is the brain of the furnace — it manages the ignition sequence, monitors safety limits and flame sensing, controls the inducer and blower motors, and coordinates the gas valve and igniter timing. When this board fails, the furnace may not start at all, may lock out after a few ignition attempts, short-cycle, or run the blower continuously. Flashing diagnostic LED codes that no longer clear after a reset, or a furnace that hums but never lights, are classic signs the control board has failed.
