The Goodman 10716005 is a genuine OEM natural gas burner orifice engineered as a direct replacement for the Amana/Goodman AMH80403ANBD 80% AFUE gas furnace. The orifice (spud) meters the exact flow of natural gas into each burner, so a worn, corroded, or incorrectly sized orifice can cause poor flame quality, delayed ignition, sooting, or nuisance lockouts. Installing the factory-drilled OEM part restores the burn characteristics your furnace was certified for.
The OEM 10716005 is factory-drilled to the precise orifice diameter matched to this furnace's BTU rating and manifold pressure — critical for safe, efficient combustion. Aftermarket orifices often vary in bore size and thread quality, which can shift the fuel/air ratio out of spec. For a combustion component, we strongly recommend the OEM part.
Moderate — Shut off gas and power before service. Removing and re-torquing the orifice on the manifold is straightforward with a nut driver, but a manometer check of manifold pressure after replacement is recommended. Gas work should be performed by a qualified HVAC technician.
