The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the GMH951155DXAA 95% AFUE gas furnace. This precision-drilled orifice meters the exact volume of natural gas delivered to each burner, setting the correct gas/air mixture for a clean, efficient flame. A worn, corroded, or incorrectly sized orifice can cause sooting, poor flame quality, or capacity loss — installing the correct OEM spud restores proper firing rate and combustion.
The OEM orifice is drilled to Goodman's specified diameter for this furnace's rated input, ensuring correct BTU output and combustion. Generic orifices may have an off-spec bore that alters the firing rate and flame quality. For combustion accuracy and safety, always use the OEM-spec orifice matched to your fuel type.
Moderate (3/5) — Shut off gas and power, remove the burner assembly or manifold, unthread the old orifice, and install the new spud to spec. Combustion should be verified after service. Best performed by a qualified technician; 30–45 minutes.
