The genuine Goodman 4053501S chimney collar forms the sealed transition between the draft hood and the vent pipe on your AMH80903BNAC 80% furnace. A warped or rusted collar can leak flue gases and disrupt proper draft — a safety-critical fault. This OEM collar restores an airtight, code-compliant vent connection.
Because this part is in the flue-gas path, fit and sealing matter for safety. The OEM 4053501S matches the factory vent opening exactly so screw holes and the pipe diameter align without gaps. Generic collars risk leaks and improper draft. OEM is strongly recommended.
Typically a 15–20 minute job: remove the vent pipe, back out the retaining screws, swap the collar, and re-seal. Verify proper draft after installation. Shut off gas and power before servicing the venting.
