Overview
This is the genuine OEM control board kit (OEM part number 1183618) for the ICP/Heil/Tempstar RGS240SSFA0AAAA gas furnace. The integrated furnace control board is the brain of the system — it sequences the inducer, igniter, gas valve, and blower, monitors safety circuits such as limit and flame sensing, and manages the timing of each heating cycle. When the board fails you may see no response to a thermostat call, blower or inducer that will not start, flashing diagnostic LED fault codes, or intermittent lockouts. This kit ships with the board and the hardware needed for a clean OEM replacement.
