ICP Furnace Control Board Kit for RGS102SRAB0AAA — OEM Integrated Control | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) brain of your ICP RGS102SRAB0AAA gas furnace. It manages the entire heating sequence — verifying safety switches, energizing the inducer, powering the hot surface igniter, opening the gas valve, monitoring flame sense, and timing the blower on and off. It also handles blower control for cooling and continuous fan modes. When the board fails, the furnace may show no response, blower-only operation, ignition lockouts, or erratic short cycling, and onboard diagnostic LED codes stop reading correctly. Supplied as a complete kit for a clean, accurate replacement, this OEM board restores proper sequencing and safety control.
