ICP Furnace Control Board for RGS102LRAA0AAA — OEM Kit 1183618 24V | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP / Heil / Tempstar RGS102LRAA0AAA gas furnace. The board is the brain of the furnace: it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and flame sense, and controls the gas valve and 24V transformer outputs. When this board fails, the furnace may fail to ignite, short-cycle, lock out, or display flashing diagnostic LED fault codes. Replacing it with a genuine OEM kit restores correct timing and safety operation without guesswork. Operates on 24VAC control voltage with onboard diagnostics and integrated relays.
