The 10716003 is a genuine OEM Goodman natural gas burner orifice (spud) for WGGE4537A090MAA gas/electric package units. The orifice threads into the manifold and meters the precise volume of natural gas fed to each burner, setting the flame characteristic and BTU input for the appliance. A worn, corroded, or incorrectly sized orifice causes poor flame quality, sooting, delayed ignition, or an out-of-spec firing rate — replacing it with the factory-correct spud restores clean, efficient combustion.
Orifice bore diameter directly controls the gas flow rate, so even a small drill-size difference changes the firing rate and combustion safety. Generic or hand-drilled orifices risk over- or under-firing the heat exchanger. The OEM 10716003 is bored to Goodman's exact specification, keeping the appliance within its rated input.
Easy to Moderate — unthread the old spud from the manifold and thread in the replacement, then leak-check. Plan 15–30 minutes. Shut off gas and power before servicing, and always leak-test with soap solution after reassembly. This part is factory-drilled for natural gas — confirm your fuel type before ordering.
