The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue component for the AMS80403AXAD 80% AFUE gas furnace and compatible Goodman/Amana models. This stamped-metal transition seats between the furnace vent outlet and the chimney/vent connector, directing combustion byproducts safely out of the appliance. A damaged, corroded, or mismatched transition can cause flue-gas leakage, poor draft, and rollout — making a factory-spec replacement important for safe operation.

Specifications

Function: Flue vent transition / vent connector base
Material: Corrosion-resistant coated steel
Location: Furnace vent outlet to chimney connector
Fits: AMS80403AXAD and compatible 80% AFUE furnaces
OEM Part Number: 0128F00006

OEM vs. Generic

OEM transitions match the exact outlet dimensions and clearances of the furnace cabinet, ensuring a tight, code-compliant vent connection. Generic sheet-metal substitutes rarely seal properly and can leave gaps that leak combustion gases. For any flue component, OEM fit is the safe choice.

Installation Difficulty

Easy (2/5). Power down the furnace, disconnect the vent pipe, remove the fasteners, and install the new transition with the original screws and approved sealant/tape where required. Verify proper draft and check for flue-gas spillage after restart. When in doubt, have a licensed technician confirm the venting.
