The Goodman 0128F00006 is a genuine OEM chimney transition bottom — a formed sheet-metal flue/vent component for the WFM18045S3AXCB gas furnace and compatible Goodman/Amana models. It bridges the furnace's flue collector to the vent connector, channeling hot combustion byproducts out of the heat exchanger toward the chimney or vent pipe. The factory geometry ensures a proper seal and correct draft path so exhaust gases exit safely.

Specifications

Type: Chimney / flue transition bottom piece
Material: Corrosion-resistant coated steel
Function: Flue-gas transition and vent connection
Fit: Goodman WFM18045S3AXCB and cross-referenced models
Mount: Screw-fastened with gasket/seal points

OEM vs. Generic

This transition is stamped to fit the exact flue-collar dimensions and draft profile of your furnace. Generic or fabricated substitutes risk poor sealing and gaps that can allow flue-gas leakage — a carbon-monoxide hazard. For any component in the venting path, the OEM part is the safe, code-appropriate choice.

Installation Difficulty

Moderate (2/5). Expect 20–40 minutes. Remove the fasteners securing the old transition, clean the mating surfaces, seat the new piece, and re-secure with sheet-metal screws and approved high-temp sealant where specified. After installation, a technician should perform a draft/spillage test and verify there are no combustion-gas leaks.

Turn off power and gas before servicing. Never operate a furnace with a compromised vent path.
