ICP Furnace Control Board Kit for RGS213HTAA0AAAA — OEM 1183618 | Ships Today

Overview

This OEM control board kit, ICP part 1183618, fits the ICP/Tempstar/Heil RGS213HTAA0AAAA gas furnace. The integrated furnace control (IFC) is the brain of the furnace — it manages the ignition sequence, inducer and blower timing, flame sensing, safety limit monitoring, and the 24V signaling between the thermostat and every major component. When the board fails you may see a furnace that is completely dead, won't respond to the thermostat, runs the blower nonstop, or flashes a fault code with no other failed parts. Supplied as a complete kit, this OEM board restores correct sequencing and safety control to the furnace.
