The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the GMH950704CXAB gas furnace. This precision-drilled brass fitting meters the exact volume of natural gas into each burner, setting the manifold firing rate and BTU output. Using the correct orifice size is essential for a clean, blue flame, proper heat exchanger temperatures, and safe, efficient combustion. The wrong drill size causes sooting, delayed ignition, or overheating.
Orifice bore diameter is a combustion-critical dimension tied to altitude and BTU rating. The OEM 10716003 guarantees the exact factory drill size and thread for this furnace. Generic or mis-sized orifices risk incomplete combustion and carbon monoxide production. Always fit the genuine OEM spud specified for your model and elevation.
Plan 30–45 minutes and treat this as a gas-side repair. Shut off gas and power, remove the burner assembly or manifold as required, unthread the old orifice with the correct wrench, and install the new spud without cross-threading or over-torquing. Leak-test all connections with soap solution before relighting. Because this affects combustion safety, professional HVAC installation is strongly recommended.
