The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) sized for the AMVC800805CNAA and compatible Goodman/Amana gas furnaces. The orifice meters the precise volume of natural gas into each burner, setting the manifold input rate and ensuring a stable, correctly proportioned flame. A worn, corroded, or incorrectly drilled orifice causes sooting, delayed ignition, lifting flames, or reduced heat output.
Orifice drill size directly controls BTU input and combustion safety. This OEM 10716005 is drilled and gauged to Goodman's spec for this furnace. Generic orifices may be close but not exact, risking over- or under-firing and CO production. For a combustion component, genuine OEM is the safe choice.
Moderate (2/5). Shut off the gas and power, remove the manifold or burner assembly, and swap the orifice with a proper wrench — do not over-torque or nick the brass. After installation, verify manifold pressure and flame appearance. A combustion analysis and leak check by a licensed technician is strongly recommended.
