The Goodman 0128F00006 is a genuine OEM chimney transition bottom for the WFD18070S3AXCB furnace. This sheet-metal transition piece connects the furnace's induced-draft flue outlet to the vent connector or chimney, forming the sealed pathway that carries combustion byproducts safely out of the home. A correctly fitted transition maintains proper draft and prevents flue-gas leakage.
Flue and venting components must fit precisely to seal against carbon monoxide leakage and maintain draft. The OEM 0128F00006 is stamped to the exact dimensions of your furnace's vent collar. Generic or field-fabricated transitions risk gaps, poor draft, and flue-gas spillage — this is a safety-related part where an exact OEM fit matters.
Moderate (3/5). The transition is fastened with sheet-metal screws and sealed at its joints. Cut power, remove the old piece, fit the new transition, and seal seams with high-temperature approved sealant or foil tape per code. Because improper venting can allow carbon monoxide into the living space, we strongly recommend a licensed technician verify draft after installation.
