The Goodman 0128F00006 is a genuine OEM chimney transition bottom for AMVC80803BXCA gas furnaces and compatible Goodman/Amana models. This flue/vent component forms the lower transition where combustion byproducts leave the furnace and enter the venting system. A properly fitted transition maintains correct draft and a sealed flue path, ensuring flue gases exhaust safely and preventing spillage of combustion products into the equipment area.
The OEM transition is stamped to the exact flange dimensions and outlet geometry of your furnace, so it seats flush and maintains a proper seal and draft. Generic or fabricated substitutes often leave gaps that leak flue gas or disrupt draft — a serious safety concern with any venting component. Choose the genuine OEM part for a guaranteed fit and safe exhaust.
Easy — Power down the furnace, remove the existing transition fasteners, seat the new part, and secure it with the factory hardware. Inspect all vent connections and confirm proper draft after installation.
