ICP Furnace Control Board Kit for RGS102LFBA0AAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part 1183618) is the integrated furnace control for the ICP / Tempstar / Heil RGS102LFBA0AAA gas furnace. It manages the entire heating sequence — inducer startup, igniter timing, gas valve operation, blower control, and all safety interlocks including limit and pressure switches. The board reads the thermostat call and orchestrates each component in the correct order. When it fails, the furnace may not respond to the thermostat, lock out on fault codes, run the blower continuously, or fail to ignite. The kit ships with the necessary mounting and connector hardware for a complete replacement.
