Goodman 0128F00006 Chimney Transition Bottom

The Goodman 0128F00006 is a genuine OEM chimney transition bottom — a flue-vent adapter that channels combustion products from the furnace draft outlet into the venting system on the WFM18115S5CXCB and compatible Goodman and Amana furnaces. Formed from corrosion-resistant sheet metal to the factory geometry, it ensures a proper, leak-resistant seal at the vent connection so exhaust gases are carried safely out of the equipment. A correctly fitted transition is critical for reliable draft and safe flue operation.

Function: Flue/vent transition at the furnace draft outlet
Material: Formed sheet metal
Location: Bottom transition of the venting connection
Fits: Goodman/Amana furnaces including WFM18115S5CXCB
Type: Direct-fit OEM replacement

OEM vs. Generic

This authentic Goodman transition matches the original dimensions, flange pattern, and mounting points exactly. Generic or field-fabricated adapters risk gaps, poor draft, and flue-gas leakage. For a component tied to safe venting, the exact OEM fit is well worth it.

Installation Difficulty

Moderate (2 of 3). Requires disconnecting the existing vent connection, removing fasteners, and reseating the new transition with proper alignment and sealing. Verify a tight vent connection and confirm correct draft after installation. Plan 20–30 minutes; always work with power and gas off and follow local venting code.
