ICP Control Board Kit for RGS240SREA0AAAA — OEM Furnace Control | Ships Today

Overview

This is the genuine ICP OEM control board kit (part number 1183618) for the RGS240SREA0AAAA gas furnace. The integrated furnace control board is the brain of the system — it sequences the ignition, manages the inducer and blower motors, monitors safety inputs like the pressure switch and limit, and responds to thermostat calls. When the board fails, the furnace may go completely dead, fail to ignite, leave the blower running continuously, or throw erratic fault codes. This OEM kit includes the correct board for a precise, reliable replacement that restores full furnace operation and safety sequencing.
