The Goodman 10716003 natural gas orifice (burner spud) is a precision-machined OEM metering component for the AMH950703BXAG gas furnace. The orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's firing rate and BTU input. A correctly sized orifice is critical for clean, efficient, and safe combustion.
Orifice bore diameter is drilled to a specific number size at the factory — even a small deviation changes the gas flow, causing sooting, delayed ignition, or over-firing. Our OEM Goodman orifice guarantees the correct bore for natural gas. Generic orifices risk incorrect drill sizing and unsafe combustion, and are not recommended for gas metering parts.
Moderate (2/5). Requires shutting off gas and power, removing the burner assembly, and threading the orifice into the manifold with a nut driver. Do not over-tighten. Leak-check all connections with soap solution after service. If converting fuel types, verify the correct orifice number — natural gas and LP orifices are not interchangeable.
Gas-fired components should be installed by a qualified HVAC technician.
