ICP Furnace Control Board Kit for RGS101HDCB0AAA — OEM Replacement | Ships Today

Overview

This genuine ICP integrated furnace control board kit (P/N 1183618) is the electronic brain of the ICP Tempstar Heil RGS101HDCB0AAA gas furnace. It sequences the entire heat cycle — energizing the inducer, proving pressure switches, firing the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on and off. It also runs continuous safety and diagnostic checks, flashing fault codes via its onboard LED. A failed control board causes no-heat, no-blower, short cycling, or erratic operation, and is often the root cause when individual components test good but the furnace still won't run correctly. The kit includes the board and mounting hardware for a complete OEM replacement.
