The 10716005 natural gas orifice (burner spud) is a genuine OEM component for the Goodman/Amana AMVC80604BXBA gas furnace. Threaded into the gas manifold, each orifice meters the exact volume of natural gas delivered to its in-shot burner, setting the furnace's BTU input and air/fuel ratio. A worn, corroded, or incorrectly drilled orifice throws off combustion, causing sooting, incomplete burn, or poor flame sense.
The OEM orifice is precision-drilled to Goodman's natural-gas specification for this furnace, protecting the correct BTU input and NOx rating. Generic or mis-sized orifices can over- or under-fire the furnace and are a safety and warranty risk. Always match the exact orifice size — do not substitute an LP orifice on a natural-gas unit.
Moderate (2/5). Threads into the manifold with a nut driver/wrench; requires shutting off gas, and a combustion/leak check after reassembly. Confirm the drill size matches your fuel type and elevation.
