The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue-venting component engineered for the Amana/Goodman AMVC800805DNAA 80% AFUE variable-speed gas furnace. This transition piece channels combustion byproducts from the heat exchanger collector box into the vent connector, maintaining the proper draft path and seal your furnace was certified with.
Genuine OEM 0128F00006 is stamped and formed to the exact heat-exchanger geometry of your Goodman/Amana furnace, ensuring a leak-free draft seal and safe flue-gas containment. Aftermarket transitions often require shimming or sealant and can void combustion certification. For a safety-critical venting part, OEM is strongly recommended.
Easy (2/5). Replaceable in 20–30 minutes with basic hand tools. Always shut off gas and power, inspect the gasket/sealant, and verify draft after reassembly. If you are unsure about combustion venting, use a licensed HVAC technician.
Ships fast from stock. Backed by our fit guarantee for the AMVC800805DNAA and related Goodman/Amana furnace platforms.
