ICP Furnace Control Board for RGS102LFCB0AAA — OEM Integrated Control | Ships Today

Overview

This OEM control board kit is the integrated furnace control (IFC) for the ICP/Heil/Tempstar RGS102LFCB0AAA gas furnace. The board is the brain of the furnace — it sequences the inducer, hot surface igniter, gas valve, and blower while monitoring safety limits and flame sense. It also stores diagnostic fault codes shown on the onboard LED. A failed board typically causes intermittent operation, no response to the thermostat, or repeated ignition lockouts. This listing covers OEM kit #1183618 (KIT CONTROL BOARD), supplied with the mounting hardware and connectors needed for a complete replacement.
