The Goodman 0128F00006 chimney transition bottom is a genuine OEM venting component for the WGFM28115V5CXAA furnace and compatible Goodman/Amana models. This sheet-metal transition connects the furnace's induced-draft/flue outlet to the vent piping, directing combustion byproducts safely out of the equipment. A corroded, cracked, or missing transition can allow flue-gas leakage and improper draft, so a correct-fitting replacement is essential for safe venting.
The OEM 0128F00006 is stamped to the exact dimensions and flange pattern of the Goodman flue outlet, ensuring a leak-free seal. Generic or fabricated transitions may not seal properly, risking flue-gas escape. For any combustion-venting part, the genuine OEM component is strongly recommended.
Easy to Moderate — disconnect the vent connector, remove the old transition, and secure the replacement with sheet-metal screws and high-temp sealant as required. Verify proper draft after install. No gas or electrical work required.
