The 10716003 is a genuine OEM natural gas main burner orifice (spud) for Goodman GCH950703BXAA gas furnaces. The orifice meters the precise volume of natural gas delivered into each burner, setting the furnace's firing rate and combustion quality. A precision-drilled orifice is essential for correct BTU input, clean blue flame, and safe operation—worn, corroded, or mismatched orifices cause sooting, delayed ignition, and improper input.
OEM orifices are drilled to the exact bore diameter Goodman rated for this furnace at your elevation and manifold pressure. Generic orifices may vary in bore size, over- or under-firing the burner and risking incomplete combustion. Because this component directly affects combustion safety, we recommend OEM.
Moderate (3/5). Requires removing the gas manifold, unscrewing the old orifice, and torquing the new one to seal. Best performed by a qualified technician who can verify manifold pressure and flame after installation. Shut off gas and power first.
