ICP Furnace Control Board for RGS102LFAB0AAA — OEM Integrated Ignition Control | Ships Today

Overview

This OEM integrated furnace control board (part #1183618, KIT CONTROL BOARD) is the brain of your ICP RGS102LFAB0AAA gas furnace. It manages the ignition sequence, monitors the flame sensor and pressure switches, sequences the inducer and blower motors, and controls gas valve timing. A failed control board is one of the most common causes of a furnace that won't ignite, short-cycles, or runs the blower continuously. The board operates on 24V control logic and includes onboard diagnostic LED fault codes to speed troubleshooting.
