The Goodman 22309501 Flue Pipe is a genuine OEM exhaust/venting component engineered for the Goodman/Amana AMV91155DXBB high-efficiency gas furnace. This flue pipe routes combustion by-products from the induced-draft blower assembly to the vent termination, maintaining the sealed, negative-pressure exhaust path that a 90%+ AFUE furnace depends on. A cracked, corroded, or leaking flue section can trip the pressure switch, cause nuisance lockouts, or allow flue gases to escape — replacing it with the correct OEM part restores safe, reliable operation.
Our OEM Goodman 22309501 is dimensionally identical to the factory part, ensuring a leak-free seal at the collar and gasket interfaces. Generic or fabricated substitutes often vary in diameter and flange fit, which can compromise the airtight exhaust path and trigger pressure-switch faults. For a safety-critical venting component, OEM is strongly recommended.
Moderate — Requires furnace shutdown, panel removal, and careful reconnection of vent couplings and gaskets. A leak or airflow check is recommended after install. If you are not comfortable working around gas venting, use a licensed HVAC technician.
