The Goodman 10716003 is a factory-spec natural gas burner orifice engineered for the Goodman/Amana GMT115-5A gas furnace and compatible multi-position models. The orifice (spud) meters the flow of natural gas into each burner, controlling the flame size and ensuring the furnace fires at its rated BTU input. A worn, corroded, or debris-clogged orifice causes lazy yellow flames, delayed ignition, soot, or short-cycling — replacing it restores clean, efficient combustion.
This is the genuine Goodman OEM orifice, drilled to the exact factory bore size for your furnace's BTU rating and gas type. Generic or universal orifices are often mislabeled or bored slightly off-spec, which can over- or under-fire the burners and create dangerous combustion conditions. For a gas-metering component, we strongly recommend the OEM part.
Requires shutting off gas and power, removing the burner assembly, and swapping the orifice with a nut driver. Best performed by a licensed HVAC technician, who should verify manifold pressure and flame appearance after installation. Always confirm your existing orifice number before ordering — bore size varies by model and elevation.
