ICP Furnace Control Board Kit for RGS091HTCA0AAA — OEM Replacement | Ships Today

Overview

This OEM furnace control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP RGS091HTCA0AAA gas furnace. The control board manages the entire heat sequence — inducer operation, hot surface igniter timing, gas valve activation, flame sensing, blower on/off delays, and all safety lockouts. It interprets thermostat calls and monitors limit and pressure switches to operate the furnace safely. A failed board causes no ignition, no blower, erratic cycling, or repeated diagnostic fault flashes. This genuine OEM kit restores correct sequencing and safety control for reliable heating.
