The Goodman 10716003 Natural Gas Orifice (burner spud) is a genuine OEM metering orifice for the WFD195070S4CAB gas furnace and compatible Goodman/Amana models. The orifice threads into the manifold and precisely meters the flow of natural gas into each burner, setting the furnace's BTU input and flame quality. A damaged, corroded, or incorrectly drilled orifice causes poor combustion — yellow or lifting flames, sooting, delayed ignition, and reduced efficiency. Installing the correct factory orifice restores clean, quiet burner performance.
Orifice sizing is precise — the drill diameter directly controls input rate and safety. The OEM orifice is drilled to Goodman's exact specification for this furnace at natural-gas pressures, guaranteeing the rated input and a proper flame. Generic or mis-sized orifices risk over- or under-firing, which can damage the heat exchanger or produce dangerous combustion. Always match OEM for gas metering parts.
Moderate (3/5). Threading in an orifice is mechanically simple, but it's part of the gas train — it should be installed by a qualified technician who can verify manifold pressure and confirm a clean flame afterward. Shut off gas and power before service. If converting fuel types, use the correct LP/NG orifice and conversion kit — do not re-drill orifices.
