ICP Furnace Control Board Kit for RGS180SRAA0AAAA — OEM | Ships Today

Overview

This genuine OEM control board kit (part #1183618) is the integrated furnace control (IFC) — the brain of your ICP, Tempstar, and Heil RGS180SRAA0AAAA gas furnace. It manages the entire heating sequence: it reads the thermostat call, energizes the inducer and igniter, opens the gas valve, monitors flame sense and pressure switches, and times the blower on and off. The board's onboard diagnostic LED flashes fault codes to speed troubleshooting. Control boards fail from voltage surges, heat stress, corroded relays, and aged solder joints — when they do, the furnace can behave erratically, lock out, or stop responding entirely.

Specifications

Compatibility

Supplied as the factory replacement kit for the ICP/Tempstar/Heil RGS180SRAA0AAAA gas furnace. As a kit, it includes the mounting and harness components needed for a direct swap. This board family is used across several ICP-brand furnaces; verify the part number and connector layout against your existing board before installing.
