The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the WGGE4348A090MAB gas furnace and compatible models. This precision-drilled brass fitting meters the exact volume of natural gas into each burner, setting the input rate and ensuring a clean, correctly sized flame. A damaged, corroded, or wrong-size orifice causes poor combustion, sooting, delayed ignition, or an under/over-fired furnace.
The OEM Goodman orifice is drilled to the factory-specified diameter for this furnace's input rating and elevation. An incorrectly sized generic orifice changes the gas input and can create dangerous combustion conditions. For a fuel-metering part, always match the OEM drill size.
Easy–Moderate (2/5). Shut off the gas and power, remove the manifold or burner assembly, thread out the old orifice with a socket, and install the replacement — do not over-tighten brass. Verify no gas leaks with soap solution and confirm a proper blue flame. Leave gas-train work to a qualified technician if you are unsure.
