ICP Furnace Control Board Kit for RGS214HDCW4BAAA | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) brain of the ICP Tempstar Heil RGS214HDCW4BAAA. It sequences the entire heating and cooling operation — managing the igniter, gas valve, inducer, blower timing, and safety lockouts based on signals from the thermostat and the system's pressure and limit switches. A failed control board can cause no-heat, no-blower, short cycling, blown fuses, or erratic operation, and is often signaled by a flashing diagnostic LED fault code. This kit ships as a complete assembly for a clean, direct replacement.
