ICP Furnace Control Board Kit for RGS102LRCA0AAA — Integrated Ignition Control | Ships Today

Overview

This OEM integrated furnace control board kit (1183618) is the "brain" of the ICP/Tempstar/Heil RGS102LRCA0AAA gas furnace. It manages the ignition sequence, monitors safety limits and flame, sequences the inducer and blower, and times the heat and cool cycles. When the board fails, symptoms can range from a completely dead furnace to erratic short-cycling, blower running constantly, or failure to ignite. Supplied as a kit for direct OEM replacement.
