The Goodman OEM 10716003 Natural Gas Orifice is a genuine precision-drilled burner spud for the AMVC950453BXAA gas furnace and compatible Goodman/Amana models. The orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's firing rate and BTU output. Because the bore diameter is machined to a tight tolerance, using the correct OEM orifice is essential for clean, efficient combustion and correct manifold pressure.
The bore of the OEM 10716003 is drilled to Goodman's exact specification for this furnace's rated input. An incorrectly sized generic orifice changes the air-fuel ratio, producing soot, delayed ignition, high CO, or under-firing. For a combustion component, only a correctly rated OEM orifice should be used — never drill or substitute by eye.
Moderate. Requires shutting off gas and power, removing the manifold or burner assembly, and threading the orifice to the correct torque. Best performed by a qualified HVAC technician who can verify manifold pressure afterward.
