The Goodman 10716005 natural gas orifice is a genuine OEM replacement for the AMVC800805CXAA gas furnace and compatible Goodman and Amana models. The orifice (spud) threads into the manifold and meters the exact volume of natural gas delivered to each in-shot burner. Its precisely machined bore is critical to correct flame size, clean combustion, and rated heating capacity. A damaged, corroded, or incorrectly drilled orifice can cause a lifting flame, sooting, low heat output, or unsafe combustion — so replacing a worn orifice with the correct OEM part is essential.
Orifice sizing is measured in thousandths of an inch and is matched to fuel type, altitude, and burner design. The OEM 10716005 guarantees the correct drill size for this furnace on natural gas. Generic or mis-sized orifices are a common cause of poor combustion and elevated carbon monoxide. Always use the exact OEM orifice.
Moderate. Shut off gas and power, remove the burner assembly to access the manifold, and unthread the old orifice with the correct wrench — taking care not to cross-thread or over-torque the brass. Reinstall, restore gas, and leak-check every joint. Budget 30–45 minutes. If you are converting fuel types or working at high altitude, consult a licensed technician for the correct orifice specification.
For natural gas only. Compatible with Goodman/Amana AMVC800805 furnaces — verify your OEM part number before ordering.
