The Goodman 10716005 Natural Gas Burner Orifice is a genuine OEM replacement engineered for AMS80603AXAA gas furnaces. This precision-drilled brass orifice (spud) meters the exact flow of natural gas into the burner, ensuring a clean, efficient flame and correct input BTU rating. A worn, corroded, or incorrectly sized orifice can cause sooting, delayed ignition, or improper heating — replacing it with the factory-spec part restores safe, reliable operation.
This is the genuine Goodman OEM orifice, drilled to the factory-specified size for the exact input rating of your furnace. Generic or aftermarket orifices may vary slightly in bore diameter, which can throw off the gas input and combustion. For a safety-critical gas component, we recommend the OEM part to guarantee correct sizing and a proper flame.
Easy (1/5). The orifice threads into the manifold and is removed with a nut driver or socket. Always shut off gas and power before servicing. If you are not comfortable working on gas components, have a licensed HVAC technician perform the replacement.
