The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) for AMS80805CXAB gas furnaces. Threaded into the manifold, the orifice meters the exact gas flow into each in-shot burner, setting the furnace's firing rate and flame quality. A damaged, corroded, or wrong-drilled orifice throws off the air-fuel mixture, causing sooting, lifting flames, or reduced heat output. Replacing with the factory-drilled orifice restores rated BTU input and clean combustion.
Orifice bore diameter directly controls gas input, so precision matters. This OEM spud is drilled to Goodman's specification for the AMS80805CXAB on natural gas. Generic orifices with an incorrect bore can over- or under-fire the furnace and defeat combustion tuning. We recommend OEM for any gas-metering part.
Difficulty: Moderate. Shut off gas and power, remove the burner assembly to access the manifold, unthread the old orifice, and install the new one to the same torque without over-tightening. About 20–40 minutes. Leak-check the manifold with the gas restored. Because it involves the gas train, licensed HVAC installation is recommended.
Verify your furnace model and fuel type before ordering. Backed by our fast-ship guarantee.
