ICP Furnace Control Board Kit for RGS150LFBA0AAAA — Ignition Control | Ships Today

Overview

This genuine OEM control board kit (part #1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS150LFBA0AAAA gas furnace. The board is the brain of the furnace: it sequences the inducer, hot surface igniter, gas valve, and blower, monitors safety limits and flame, and manages the 24V thermostat call. When it fails you may see a dead furnace with no response to the thermostat, no inducer start, blinking diagnostic LED fault codes, intermittent operation, or blower running continuously. This kit ships with the mounting hardware needed for a complete replacement.
