The Goodman 10716005 is a genuine OEM natural-gas burner orifice (spud) for the VMS80403ANAA gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the furnace's BTU input and ensuring a clean, correctly proportioned flame. A damaged, clogged, or wrong-size orifice causes poor combustion, sooting, delayed ignition, or incorrect heat output.
The genuine Goodman OEM orifice is drilled to the exact bore size specified for this furnace's rated input and altitude. Using the wrong drill size — common with unmarked generic spuds — over- or under-fires the burner and can create an unsafe flame. Match the OEM number for correct, safe combustion.
Moderate (3/5). A gas-side repair best handled by a qualified technician. Shut off gas and power, remove the manifold or unthread the orifice, install the correct replacement, and leak-check all joints before firing. Typical time: 20–40 minutes. Verify manifold pressure and flame after installation.
