The Goodman 10716005 Natural Gas Orifice is a genuine OEM replacement part engineered for the AMEC800603BNAB gas furnace and compatible Goodman/Amana models. This precision-drilled brass orifice (spud) meters the exact flow of natural gas into the burner, ensuring the correct BTU input, a clean blue flame, and safe, efficient combustion. A worn, corroded, or incorrectly sized orifice can cause sooting, poor flame, or unsafe operation — replacing with the factory-specified part restores proper performance.
This is a genuine OEM Goodman orifice, drilled to the manufacturer's exact specification. Generic orifices are cheaper but often vary in bore diameter, which changes the gas flow and can throw off the furnace's BTU rating. For a safety-critical gas component, OEM is the recommended choice.
Easy (1/5) — Shut off gas, remove the manifold/burner, thread out the old spud and thread in the new one. Basic hand tools required. If you are not comfortable working with gas connections, hire a licensed HVAC technician.
