ICP Furnace Control Board Kit for RGS240HDAA0AAAA — OEM Integrated Control | Ships Today

Overview

This genuine OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS240HDAA0AAAA gas furnace. The board is the brain of the furnace: it manages the ignition sequence, runs safety interlocks, controls the inducer and blower timing, and reads the flame-sense signal. Supplied as a complete kit with the correct board and mounting hardware, it is the right replacement when the board has failed from a power surge, corroded relay, or burned trace. Most boards include an LED diagnostic that flashes fault codes to speed troubleshooting.
