The 0128F00006 is a genuine OEM Goodman/Amana chimney transition bottom for the AMH81005CXAA gas furnace. This sheet-metal transition channels flue products from the heat-exchanger collector box into the vent connector/draft hood, forming a critical part of the furnace's venting path. A rusted, warped, or corroded transition can leak combustion gases, disrupt draft, and compromise safe venting — this exact-fit OEM replacement restores a proper, sealed flue connection.
The OEM 0128F00006 is stamped to the exact dimensions and flange pattern Goodman designed for this cabinet, ensuring gaskets seat and screw holes align for a gas-tight fit. Generic or fabricated transitions often leak at the seams or misalign the vent, risking spillage of combustion gases. For a venting component, genuine OEM is the recommended, safety-critical choice.
Moderate (3/5). Requires disconnecting the vent connector, removing fasteners and gasket/sealant, fitting the new transition, and re-sealing all joints. A combustion/draft check after installation is strongly advised. Shut off power and gas first. Best handled by an HVAC professional; typically 30–45 minutes.
