ICP Furnace Control Board Kit for RGS240SRAA0AAAA — OEM Ignition Control | Ships Today

Overview

This genuine OEM control board kit (part #1183618) is the integrated furnace control (IFC) for the ICP RGS240SRAA0AAAA. It is the brain of the furnace: it manages the ignition sequence, sequences the gas valve and igniter, controls the inducer and blower motors, monitors safety limits and flame sense, and runs the timing for each heat and cool cycle. The kit ships with the board and mounting hardware needed for a complete replacement. A failed board is a common cause of a furnace that is completely dead, won't sequence, or repeatedly faults — often indicated by diagnostic LED error codes.
