The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the AMVC80805DNBC 80% variable-speed gas furnace. This precision-drilled brass jet threads into the manifold and meters the exact volume of natural gas delivered to each in-shot burner. The orifice bore is sized to the furnace's BTU rating and gas type, making it critical to safe, efficient combustion.
A clogged, corroded, or wrong-size orifice causes a weak or oversized flame, poor efficiency, sooting, or improper gas input. Replacing a damaged spud with the correct OEM part restores the factory-rated firing rate.
Orifice drill size directly controls gas input (BTU) — even a fraction of a millimeter changes the flame. Genuine OEM orifices are bored to Goodman's exact specification for your model and altitude default. Generic or mis-sized spuds risk over/under-firing and unsafe combustion. Always match the OEM number.
Moderate (3/5). Shut off gas and power, remove the manifold or burner as needed, and thread out the old orifice with the correct wrench. Do not over-torque or enlarge the bore. Leak-test all connections after install.
