The Goodman 10716003 natural gas orifice (spud) is a genuine OEM burner component for GMH950703BXAE 95% AFUE gas furnaces. Each orifice is precision-drilled to meter the exact gas flow required for clean, efficient combustion and rated BTU output. A worn, corroded, or incorrectly-sized orifice causes lazy flames, sooting, delayed ignition, or under-firing — replacing it restores a crisp blue flame and proper heat rise.
The genuine OEM Goodman orifice carries the factory-calibrated drill size for the model's BTU rating — critical for safe combustion. Generic orifices may be mislabeled or drilled off-spec, risking improper firing and CO production. For a gas-carrying part, always use OEM and match the drill number to your model.
Moderate. Requires shutting off gas, removing the burner assembly, and threading in the new orifice. Recommended for experienced DIYers or a licensed technician; verify manifold pressure after installation.
Turn off gas and power before servicing. Gas-side repairs should be verified by a licensed HVAC professional.
