The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the AMVC81005CXBD furnace. The orifice meters the precise volume of natural gas delivered into each in-shot burner, setting the BTU input and flame quality. A damaged, clogged, or incorrectly sized orifice throws off the air/fuel ratio, producing sooting, lazy yellow flames, or reduced heat output. Precision drilling is critical — a few thousandths of an inch changes the firing rate.
The factory OEM Goodman orifice is drilled to the exact diameter matched to this furnace's manifold pressure and burner design. Generic or hand-drilled orifices risk over- or under-firing, which affects efficiency, CO output, and heat-exchanger life. For gas metering components, OEM is the only safe choice.
Moderate (3/5). Shut off gas and power, remove the manifold or unthread the orifice from the manifold with the correct wrench, and thread in the replacement snugly without over-tightening (brass strips easily). Leak-check all joints and confirm a clean blue flame and correct manifold pressure after installation. A licensed technician is recommended.
