The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) precision-drilled for the AMH950905CXAC gas furnace. The orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's rated BTU input and ensuring a clean, correctly-shaped flame. Because the bore is factory-sized to the model's gas pressure and firing rate, using the specified orifice is essential for safe, efficient combustion.
The OEM Goodman orifice guarantees the correct drill size for this furnace's manifold pressure and altitude spec, so the burner fires at the designed input. A generic or mis-sized orifice — or a natural-gas orifice used where LP was required — causes over- or under-firing, sooting, delayed ignition, or a dangerous flame. Always match the orifice to the fuel and model. This is a safety-critical combustion part; OEM is strongly recommended.
Moderate (3/5). Requires shutting off the gas, removing the manifold or burner assembly, and backing out the old spud with a properly-sized deep socket or nut driver. Reinstall snugly without over-tightening (brass strips easily), then leak-check every joint with soap solution and confirm proper flame on startup. Gas work should be performed by a qualified technician.
