ICP Furnace Control Board Kit for RGS180HSEA0AAAA — OEM 1183618 | Ships Today

Overview

This genuine ICP OEM control board kit (part number 1183618) is the factory replacement integrated furnace control (IFC) for the RGS180HSEA0AAAA. The control board is the brain of the furnace — it sequences the inducer, igniter, gas valve, and blower, monitors safety circuits, and manages timing and diagnostics. When the board fails you may see no response to thermostat calls, a stuck blower, erratic cycling, or flashing fault codes on the diagnostic LED. Supplied as a complete kit, this OEM board restores correct ignition sequencing and safety control for reliable, code-compliant operation.
