Icp 1183390 Heat Exchanger Kit

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1183390 is a genuine OEM replacement heat exchanger kit engineered for residential gas furnace applications. The heat exchanger is the core component responsible for transferring combustion heat to the air stream while keeping flue gases isolated from conditioned air. A failed or cracked heat exchanger is a safety hazard, and using an OEM replacement ensures the part meets original design tolerances for thermal cycling, sealing, and airflow geometry. This kit measures 20.2 inches in length, 15 inches in width, and 3 inches in height, and weighs 6.5 pounds. Licensed HVAC technicians handle this replacement as part of furnace service or inspection work.

This heat exchanger kit is suited for residential forced-air gas furnace systems where the original heat exchanger has cracked, corroded, or failed inspection. It restores the thermal separation between the combustion chamber and the supply air plenum, which is critical for carbon monoxide safety and heating efficiency. Installation is performed during furnace servicing when a visual inspection, pressure test, or combustion analysis reveals exchanger failure. Verify the part number against the unit nameplate before ordering to confirm fitment.
