The Goodman 10716005 is a genuine natural gas burner orifice (spud) for the AMES920403ANAA gas furnace. The orifice meters the precise volume of natural gas fed into each in-shot burner, setting the gas-air ratio that determines flame quality, BTU output, and combustion safety. A damaged, corroded, or incorrectly drilled orifice throws off the mixture, causing sooting, poor efficiency, or unsafe combustion — the correct factory orifice keeps input rate on-spec.
The genuine Goodman 10716005 is precision-drilled to the exact orifice diameter certified for the AMES920403ANAA at its rated BTU input. Generic or field-drilled orifices risk over- or under-firing the furnace, which affects efficiency, flame safety, and warranty coverage. For gas-metering components, always use the OEM orifice sized for your fuel type — do not substitute an LP orifice for natural gas.
Moderate. Threads into the manifold in place of the old orifice; 20–30 minutes, but requires removing burners and confirming manifold pressure afterward. Gas-metering work should be done by a licensed HVAC technician. Shut off gas and power first, and leak-test all connections before firing.
