The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM gas spud built for the AMS80905CNAA furnace and compatible Goodman and Amana models. Threaded into the burner manifold, this orifice meters the exact flow of natural gas to each in-shot burner, setting the furnace's firing rate and BTU input. When an orifice becomes clogged, eroded, or is the wrong size, you'll see yellow-tipped flames, sooting, or under-firing — replacing it with the factory-spec orifice restores clean, rated combustion.
The bore diameter of this OEM orifice is drilled precisely to Goodman's natural-gas specification, guaranteeing correct manifold pressure and gas/air ratio. Generic orifices with even slightly different bores can over- or under-fire the furnace, cause sooting, or create unsafe combustion. For a fuel-metering component, OEM is the safe choice.
Moderate. Approximately 15–30 minutes for a full set. Shut off the gas, remove the manifold, and swap the orifices with a nut driver. A post-install combustion and manifold-pressure check is recommended — ideally verified by a qualified HVAC technician.
