This genuine OEM Goodman 10716005 Natural Gas Burner Orifice (also called a spud) meters the flow of natural gas into the burner of your AMVC800604BXAB furnace and compatible Goodman/Amana models. The orifice is precision-drilled to a specific diameter that delivers the exact BTU input your furnace was engineered for. Over time orifices can enlarge from erosion, clog with debris, or be damaged during service — any of which throws off the air-fuel mixture and can cause sooting, delayed ignition, or reduced heat output.
OEM vs. Generic: The Goodman OEM 10716005 is drilled to the manufacturer's exact orifice size and thread spec for your model, so the burner fires clean and to rating. Generic orifices are sometimes sold by nominal drill number only and may not match Goodman's manifold pressure calibration, risking incorrect BTU input, poor flame quality, and safety concerns. For a combustion component, match the OEM part.
Installation difficulty: Easy (2 of 5). Replacement takes roughly 20–30 minutes for a trained tech. Shut off gas and power, remove the burner assembly or manifold as needed, unthread the old orifice with the correct wrench, and thread in the new one — do not overtighten. After installation, verify manifold pressure and inspect the flame pattern. If converting fuel types, use the correct conversion orifice and follow all local codes; this part is for natural gas.
