The Goodman 0128F00006 is a genuine OEM chimney transition bottom for the AMS80604BXAD 80% AFUE gas furnace and compatible Goodman/Amana models. This sheet-metal venting component connects the furnace's induced-draft outlet to the flue/vent pipe, channeling combustion byproducts safely up the chimney. A corroded, warped, or missing transition can cause flue-gas leakage, poor draft, and pressure-switch faults.
This genuine OEM transition is stamped to your furnace's exact cabinet dimensions and vent geometry for a leak-free seal. Generic or hand-fabricated substitutes rarely match the original flange and can compromise draft and safety. OEM guarantees a proper, gasket-ready fit.
Easy to Moderate — power off the furnace, remove the existing transition screws, seat the new part, and reseal joints with approved high-temp material. A confident DIYer can handle it; verify draft and check for flue-gas leaks after installation.
