The Goodman 0128F00006 is a genuine OEM chimney transition bottom that connects the furnace flue collector to the venting system on the AMVC800803BNAA and other compatible Goodman and Amana gas furnaces. This sheet-metal transition channels combustion byproducts from the induced-draft blower into the vent pipe or chimney, maintaining proper draft and a sealed flue path. A corroded, warped, or missing transition can cause draft problems, flue-gas spillage, and pressure-switch faults.
Because this transition is stamped to the precise dimensions of the AMVC800803BNAA vent outlet, the OEM Goodman part drops in without modification and seals correctly. Generic or fabricated substitutes often require trimming, extra sealant, and risk leaks in the flue path — an area where a proper seal is essential for safe venting of combustion gases.
Easy to Moderate. With power off, remove the fasteners securing the old transition, clean the mating surface, and install the replacement using the original screws and appropriate high-temp sealant if specified. Confirm the vent connection is tight and inspect draft after startup.
