The Goodman 10716003 is a genuine OEM natural-gas burner orifice (spud) for AMS950905DXA gas furnaces and compatible Goodman/Amana models. The orifice threads into the manifold and meters the precise volume of natural gas delivered to each burner, setting the furnace's firing rate and combustion quality. Using the exact factory-drilled orifice is critical: an oversized or mismatched hole causes sooting, delayed ignition, and dangerous over-firing, while an undersized one starves the flame. This part restores clean, correctly rated combustion.
OEM orifices are drilled and gauged to the manufacturer's exact input rating and altitude derating. Generic drill-your-own spuds risk incorrect BTU output and unsafe combustion. Because this part directly affects gas metering, the factory-specified orifice is the only safe choice.
Moderate (3/5) — gas work. Shut off the gas valve and power, remove the manifold or burner assembly, back out the old orifice with a nut driver, and thread in the new one snugly without over-torquing. Afterward, leak-test all joints with soap solution and verify manifold pressure. If you are not comfortable working on gas piping, have a licensed HVAC technician perform this replacement. Roughly 30–45 minutes.
