ICP Furnace Control Board Kit for RGS214HEAA0AAAA — OEM 1183618 | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) that manages the entire heating sequence in your ICP / Heil / Tempstar RGS214HEAA0AAAA. It sequences the inducer motor, ignition, gas valve, blower, and safety circuits while monitoring limit switches, pressure switches, and flame sense. Supplied as a complete kit with the necessary hardware for a clean replacement. When the board fails, the furnace may not respond to a heat call at all, may short-cycle, blow the blower without ignition, or flash diagnostic fault codes through the onboard LED.
