ICP Furnace Control Board Kit for RGS102HDAB0AAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS102HDAB0AAA. The control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety inputs like the pressure switch and flame sensor, and stores diagnostic fault codes on its onboard LED. When the board fails, the furnace may fail to ignite, short-cycle, blow cold air, or stop responding to the thermostat entirely. This kit includes the OEM board for an exact electrical and mounting fit, restoring full sequencing and safety control.
