The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the GMH950704CXAF 96% AFUE two-stage gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the flame size and BTU input. A correctly sized, undamaged orifice is essential for clean, efficient combustion and safe operation — a worn, clogged, or wrong-size orifice can cause sooting, poor efficiency, or unsafe flame characteristics.
OEM vs. Generic: The OEM 10716003 is drilled to Goodman's exact orifice diameter for the model's rated BTU input and gas pressure. Generic orifices can have inconsistent bore sizes that throw off the fuel-air ratio, hurting efficiency and safety. For a combustion component, OEM precision matters.
Install difficulty: Moderate — 3 out of 5. Requires a nut driver or wrench to remove the manifold spud and care not to cross-thread or over-tighten. Always shut off the gas supply and power. We strongly recommend a licensed HVAC technician verify manifold pressure and flame after replacement.
