The Goodman 10716003 natural gas burner orifice is the genuine OEM metering spud for the WFD195045S3BAA furnace. Threaded into the manifold, each orifice meters a precise volume of natural gas into its burner so the flame burns clean and at the rated BTU input. A damaged, corroded, or incorrectly sized orifice causes poor flame quality, sooting, delayed ignition, or reduced heat output — and can compromise safe combustion.
Orifice drill size directly controls the gas input rate, so the OEM Goodman orifice is the safest choice — it is bored to the exact size specified for this furnace and fuel type. Never substitute an unmarked or LP orifice on a natural-gas furnace; incorrect sizing affects combustion safety. Choose OEM for a guaranteed match.
Moderate (2 of 5). About 20–30 minutes and involves working on the gas manifold. Shut off gas and power, unthread the old orifice with the correct wrench, and install the replacement without overtightening or cross-threading. Always leak-test all gas joints with soapy water before returning the furnace to service. If you are not confident working on gas piping, hire a licensed HVAC technician.
