The Goodman 10716003 is a genuine OEM natural-gas burner orifice (spud) for the WGFM195045S3BAB gas furnace. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's input rate and flame quality. A worn, corroded, or incorrectly sized orifice causes poor combustion, sooting, delayed ignition, or a furnace that will not reach rated output.
Orifice bore diameter is critical and specific to fuel type, altitude, and furnace input. Even a slightly oversized or undersized generic orifice changes the BTU input and can create unsafe combustion. Always use the genuine OEM orifice matched to your furnace and fuel — do not substitute an LP orifice for natural gas.
Plan on 20–40 minutes. This job involves opening the gas manifold, so shut off gas and power first. Remove the burners as needed, thread out the old orifice, and install the new one snugly without over-torquing the soft brass. After installation, always leak-test all joints with soapy water and verify the flame. If you are not experienced with gas manifolds, use a licensed HVAC technician.
Confirm the part number and fuel type on your existing orifice before ordering.
