ICP Furnace Control Board Kit for RGS243HTEA0AAAA — OEM Integrated Ignition Control | Ships Today

Overview

This OEM control board kit (P/N 1183618) is the integrated furnace control (IFC) module that manages the entire heating sequence on the ICP/Tempstar/Heil RGS243HTEA0AAAA. It coordinates the inducer motor, igniter, gas valve, blower timing, and safety circuits while monitoring limit and flame-sensing inputs and storing diagnostic fault codes. When the board fails, the furnace may not respond to thermostat calls, skip ignition, short-cycle, run the blower continuously, or flash error codes. This complete kit includes the board and the mounting hardware needed for a clean OEM replacement that restores full furnace control and safety functions.
