Goodman 0128F00006 Chimney Transition Bottom

The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM sheet-metal vent component that channels flue gases from the furnace's induced-draft blower up into the chimney or vent connector. It is a direct-fit replacement for the transition panel used on the Goodman GDH80403ANBB and other 80% AFUE gas furnaces built on the shared Goodman/Amana platform. A rusted-through, warped, or missing transition can leak combustion products, spoil draft, and trigger pressure-switch faults or spillage — making this an important part to keep in good condition.

Specifications

OEM Part Number: 0128F00006
Type: Chimney / flue transition, bottom panel
Material: Corrosion-resistant coated steel
Fits Model: GDH80403ANBB (and compatible Goodman/Amana furnaces)
Equipment: Gas Furnace, 80% AFUE (induced draft)
Brand: Goodman (genuine OEM)

OEM vs. Generic

The genuine Goodman OEM transition matches the factory flue opening, gasket surfaces, and screw pattern so it seals correctly against the vent and blower housing. Generic or shop-fabricated panels risk gaps that leak flue gas or disrupt draft — a carbon-monoxide safety concern. OEM is strongly recommended for any vent-path part.

Installation Difficulty

Moderate (2/5). Turn off power and gas, disconnect the vent connector, remove the fasteners securing the old transition, and install the replacement with proper gasketing/sealant per the furnace instructions. Plan for ~30 minutes and verify draft and pressure-switch operation afterward. Combustion-vent work is best done by a qualified technician.

Compatibility note: verify model/serial and vent configuration before ordering. Contact info@nationalhvacparts.com.

Is this flue / vent transition compatible with Bryant or Payne too?

To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Goodman flue / vent transition?
