ICP Integrated Furnace Control Board for RGS102HRCA0AAA — OEM Kit | Ships Today

Overview

This OEM ICP control board kit (part #1183618) is the integrated furnace control (IFC) that runs the entire heating sequence on the RGS102HRCA0AAA. The board manages ignition timing, gas valve sequencing, inducer and blower operation, safety lockouts, and self-diagnostics via its onboard fault LED. When the board fails — from voltage surges, corroded relays, cracked solder joints, or burned traces — the furnace may not respond to the thermostat, skip ignition, run the blower constantly, or flash error codes. Replacing the control board with the correct OEM kit restores proper sequencing and safety control.
