The Goodman 10716003 is a factory-drilled natural gas burner orifice (spud) engineered as a direct-fit replacement for the WFD195045S3BAB gas furnace and compatible Goodman/Amana models. The orifice threads into the manifold and meters the exact volume of natural gas delivered to each burner, ensuring a clean flame, correct BTU input, and safe, efficient combustion. A worn, corroded, or mis-drilled orifice can cause sooting, delayed ignition, or an incorrect firing rate — installing the genuine OEM spud restores the furnace to its rated specifications.
The genuine OEM orifice is drilled to Goodman's precise factory bore diameter for this furnace's rated input. Generic or aftermarket spuds often use a nominal drill size that shifts the BTU rate and can trip flame-sensing faults or produce a lazy flame. For a gas-metering component, the OEM part is strongly recommended to protect combustion safety and efficiency.
Moderate — licensed HVAC technician recommended. Requires shutting off the gas supply, removing the manifold or burner assembly, and verifying manifold pressure after replacement. Any gas-side work should meet local code and be leak-tested.
