The Goodman 10716003 is a genuine OEM natural gas burner orifice (gas spud) precisely drilled to meter the correct fuel flow into each burner of the WFD195070S3BAA gas furnace and compatible Goodman and Amana models. The orifice size determines the BTU input and directly affects flame quality, combustion efficiency, and safe operation. A worn, damaged, or incorrectly sized orifice causes poor flames, sooting, delayed ignition, or improper heat output — so matching the factory part is essential.
Orifice sizing is safety-critical. The OEM Goodman orifice is drilled to the exact diameter your furnace was certified with. A generic orifice with even a slightly different bore changes the firing rate and can over-fire or under-fire the appliance. Always use the OEM-matched part for natural gas.
Moderate (2/5). Shut off gas and power, remove the manifold or burner as required, thread out the old orifice with the correct socket/wrench, and install the new one snugly without over-torquing. Leak-test all gas connections with soap solution before relighting. Recommended for experienced DIYers or an HVAC technician.
