ICP Furnace Control Board for RGS102LTBA0AAA — OEM Ignition Board Kit | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) brain of the ICP / Heil / Tempstar RGS102LTBA0AAA gas furnace. It sequences the ignition cycle, monitors flame and safety switches, controls the inducer and blower motors, and manages timing for heating and cooling calls. When this board fails, the furnace may fail to ignite, lock out intermittently, run the blower continuously, or stop responding to the thermostat entirely. This kit ships with the correct board and mounting hardware for a direct OEM replacement.
