The Goodman 10716003 is a genuine OEM natural gas burner orifice built for the Goodman/Amana AMS80905CXAA gas furnace and related 80% AFUE units. This spud threads into the manifold and precisely meters gas to each burner, delivering the correct BTU input and a crisp blue flame. Over time orifices can clog with dust or corrode, leading to weak flames, ignition faults, and lost efficiency — a fresh OEM orifice returns combustion to factory specification.
This genuine Goodman orifice is drilled to the exact factory bore for the AMS80905CXAA's rated gas input and manifold pressure. Generic substitutes with an incorrect bore can over-fire or under-fire the burner, causing sooting, rollout trips, or unsafe combustion. For gas components, matching OEM is the safe choice.
Rated Easy (1/5) for a trained tech. Turn off gas and power, pull the burner assembly, swap the orifice, and reassemble — no sizing calculations needed. Check manifold pressure and flame quality after installation. Gas work must be done by a licensed HVAC professional.
