ICP Furnace Control Board Kit for RGS180HREA0AAAA — Integrated Furnace Control | Ships Today

Overview

This OEM control board kit (part number 1183618, "Kit Control Board") is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS180HREA0AAAA gas furnace. The board manages the complete heating sequence: it powers the inducer, energizes the hot surface igniter, opens the gas valve, monitors the flame sensor, and times the blower on/off delays. It also runs onboard safety logic and flashes diagnostic fault codes via an LED. When the board fails, the furnace may be completely dead, stuck on the blower, or unable to complete an ignition sequence.
