ICP Furnace Control Board Kit for RGS101SRCB0AAA — OEM Ignition Control | Ships Today

Overview

This genuine OEM control board kit (part #1183618) is the integrated furnace control (IFC) for ICP, Heil, and Tempstar gas furnaces. The board manages the entire heating sequence — inducer startup, igniter warm-up, gas valve timing, flame sensing, and blower control — and runs the safety logic that locks out the furnace on a fault. A failed board typically shows as a furnace that won't start, erratic blower behavior, or repeated diagnostic fault codes from the onboard LED.
