The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) for the AMH80805CNBC gas furnace and compatible Goodman/Amana models. Threaded into the manifold, the orifice precisely meters the volume of natural gas delivered to each in-shot burner, establishing the furnace's rated BTU input and a clean, efficient flame. A drilled-out, corroded, or incorrectly sized orifice causes poor combustion, sooting, or an over/under-fired furnace.
Orifice bore size directly controls the gas input, so the genuine Goodman OEM spud is drilled to the exact factory specification for this model's firing rate and elevation. Generic orifices risk mismatched bores that upset the air/fuel ratio. Use OEM to keep combustion safe and efficient.
Moderate (3/5). Shut off the gas, remove the manifold or burner to access the orifice, and thread in the replacement — do not overtighten the soft brass. Verify flame appearance and check for leaks with soap solution after install; professional service recommended.
