Overview
The OEM Integrated Furnace Control (IFC) board kit 1183618 governs the entire heating sequence on your ICP/Heil/Tempstar RGS243SDEA0AAAA gas furnace — managing ignition timing, inducer and blower operation, flame sensing, and safety lockouts. When the board fails the furnace may not respond to the thermostat, may lock out repeatedly, or may run the blower continuously. This complete factory replacement kit is supplied as ICP part number 1183618 and restores full diagnostic and control function.
