The 0128F00006 chimney transition bottom is a genuine OEM flue/vent component for the Goodman/Amana AMVC80604BXBA gas furnace. This formed sheet-metal transition connects the furnace's induced-draft outlet to the vent/chimney connector, channeling combustion byproducts safely out of the cabinet. A rusted, misaligned, or damaged transition can leak flue gases or disrupt draft, triggering pressure-switch faults and safety concerns.
The OEM transition is stamped to the exact flange, offset, and outlet diameter of the AMVC80604 cabinet, ensuring a tight draft seal and proper vent alignment. Generic transitions rarely match the induced-draft outlet geometry and can create leaks or improper draft. For a venting component, OEM fit is essential to safety.
Moderate (2/5). Involves removing sheet-metal screws, resealing joints with high-temp foil tape/sealant, and verifying draft. Power and gas off; a combustion-analyzer/draft check is recommended after replacing any venting part.
