ICP Furnace Control Board Kit for RGS102HDBA0AAA — Integrated Ignition Control | Ships Today

Overview

This is a genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS102HDBA0AAA gas furnace. The integrated furnace control board is the brain of the appliance: it manages the ignition sequence, sequences the inducer motor and blower, monitors safety limits and the flame signal, and provides the 24V control circuit for cooling. When the board fails, the furnace may not respond to the thermostat at all, the inducer or blower may run erratically, or the unit may repeatedly lock out. This kit ships with mounting hardware and instructions for a direct replacement of the original board.
