ICP Integrated Furnace Control Board for RGS240SEEA0AAAA — Replacement Kit | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS240SEEA0AAAA gas furnace. The board is the brain of the furnace — it sequences the inducer, igniter, gas valve, and blower, monitors the pressure switch and limit safeties, and reads the flame signal to confirm a clean light. When the board fails you'll see no response to a heat call, blower or inducer that won't start or won't stop, blinking diagnostic LED fault codes, or intermittent lockouts. This kit includes the replacement board so you can restore full, code-correct furnace operation and clear nuisance no-heat faults.
