ICP Furnace Control Board Kit for RGS240HRAA0AAAA — OEM Replacement | Ships Today

Overview

This OEM control board kit (ICP part 1183618) is the integrated furnace control (IFC) for the ICP / Heil / Tempstar RGS240HRAA0AAAA gas furnace. The board is the brain of the furnace — it sequences the inducer, ignition, gas valve, and blower while monitoring the pressure switch, limits, and flame-sense circuit. The kit ships with the mounting hardware and instructions needed for a complete swap. A failed board shows up as a furnace that's completely dead, won't begin a heat cycle, locks out on safety, or runs the blower continuously. Replacing the board restores correct sequencing and safe operation.
