ICP Furnace Control Board Kit for RGS180SFEA0AAAA — Integrated Ignition | Ships Today

Overview

This genuine ICP / Heil / Tempstar control board kit (OEM part #1183618) is the integrated furnace control (IFC) that manages the entire heating and blower sequence on the RGS180SFEA0AAAA. It governs ignition timing, gas valve operation, inducer and blower relays, safety lockouts, and flame sensing, while reading the thermostat and limit/pressure switches. A failed board is one of the most common causes of a furnace that is completely dead, won't ignite, runs the blower continuously, or flashes diagnostic fault codes. This kit ships with the board and mounting hardware needed for a direct replacement.
