The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the AMH950453BXAB 95% AFUE gas furnace. This precision-drilled fitting meters the flow of natural gas into each burner, setting the flame size and BTU input. The orifice bore is machined to the exact size Goodman specifies for this furnace's rated input and manifold pressure, so it produces a clean, correctly-sized flame and proper heat-exchanger performance.
Orifice sizing is exact — even a fraction of a drill-size difference over- or under-fires the burner, causing sooting, delayed ignition, or a cracked heat exchanger over time. Generic "universal" orifices are frequently mis-drilled. The OEM 10716003 guarantees the factory bore for this natural-gas application, which is why we recommend OEM for any fuel-metering part.
Intermediate. Requires shutting off the gas supply, removing the burner assembly or manifold, and threading the new orifice to the correct torque without damaging the seat. After installation, gas fittings must be leak-checked and the flame and manifold pressure verified. Fuel-side work is best performed by a licensed technician.
