ICP Furnace Control Board Kit for RGS180HTAA0AAAA — OEM Ignition Control | Ships Today

Overview

This genuine OEM control board kit, part 1183618, is the integrated furnace control (IFC) for the ICP/Heil/Tempstar RGS180HTAA0AAAA gas furnace. The control board is the brain of the furnace — it sequences the inducer, igniter, gas valve, and blower, monitors flame and safety switches, and manages the 24V thermostat circuit. The kit ships as a complete assembly for a direct replacement. When a control board fails you may see a blank or flashing diagnostic LED, no response to a heat call, the blower or inducer running continuously, intermittent lockouts, or scrambled ignition sequencing. Replacing a failed board restores correct, safe operating sequence and clears persistent fault codes.
