The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud built for the ACVC951155DXAA gas furnace and related Goodman/Amana models. The orifice meters the precise volume of natural gas delivered to each burner, setting the flame size and BTU input for clean, efficient combustion. A worn, corroded, or incorrectly sized orifice throws off the air-fuel ratio and can cause sooting, poor efficiency, or burner noise.
OEM orifices are drilled to a factory-controlled bore diameter matched to your furnace's manifold pressure and BTU rating. Generic orifices vary in bore tolerance and thread pitch — even a small deviation changes firing rate and combustion quality. For a fuel-metering part, the OEM bore spec is what keeps the furnace within its rated input.
Easy to Moderate. Threads into the manifold and is removed with a nut driver or socket — usually a 10–20 minute job. Shut off gas and power first, and verify manifold pressure with a manometer after installation. Converting between natural gas and LP requires the proper conversion kit, not just an orifice swap.
