ICP Furnace Control Board Kit for RGS180LDEA0AAAA – OEM Replacement | Ships Today

Overview

This genuine OEM integrated furnace control board kit (Part No. 1183618) is the brain of the ICP/Tempstar/Heil RGS180LDEA0AAAA gas furnace. It sequences ignition, manages the inducer and blower timing, monitors flame and limit safeties, and runs onboard diagnostics via its LED fault codes. Supplied as a complete kit with mounting hardware and instructions, it replaces a board that has failed due to power surges, heat stress, cracked solder joints, or a blown onboard fuse. A failed control board typically shows as no response on a call for heat, blower or inducer that won't cycle correctly, or a board that no longer flashes diagnostic codes.
