ICP Furnace Control Board Kit for RGS180HECA0AAAA — OEM 1183618 | Ships Today

Overview

This genuine ICP control board kit (OEM part number 1183618) is the integrated furnace control for the RGS180HECA0AAAA platform, supplied as a complete kit with the mounting hardware and instructions needed for a clean swap. The control board is the brain of the furnace: it sequences the inducer, igniter, gas valve, and blower, monitors safety switches and flame, and manages timing and lockouts. When it fails you may see no response to a heat call, blower or inducer problems, error-code flashing, or random lockouts. Replacing it with the correct OEM kit restores the full, safe ignition and operating sequence.
