ICP Control Board Kit for RGS240LSEA0AAAA — Furnace Ignition Control | Ships Today

Overview

This OEM control board kit (part #1183618) is the integrated furnace control that orchestrates the entire heating sequence in your ICP RGS240LSEA0AAAA package unit. It manages the inducer motor, hot surface igniter, gas valve timing, blower operation, and all safety interlocks including limit and flame-sensing circuits. When a control board fails, the result is erratic behavior — no ignition, blower running constantly, or the unit ignoring thermostat calls entirely. This kit ships with the mounting hardware and instructions needed for a complete replacement.
