ICP Furnace Control Board Kit for RGS101LFCB0AAA | Ships Today

Overview

This OEM integrated furnace control board kit (part #1183618) is the brain of the ICP, Heil, and Tempstar RGS101LFCB0AAA gas furnace. It sequences the ignition cycle, manages inducer and blower timing, monitors flame sense and limit/safety switches, and runs the diagnostic LED fault codes. A failed board is one of the most common causes of a dead furnace: no response on a heat call, blower that won’t start or won’t shut off, intermittent operation, or flashing fault codes that point to the board itself. The kit ships with the board and mounting hardware for a direct replacement.
