The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the WGFD293070V4CAB gas furnace and compatible Goodman/Amana models. The orifice meters the precise volume of natural gas delivered into each burner venturi, setting the furnace's BTU input and combustion mix. A worn, corroded, or wrong-size orifice throws off the fuel-air ratio, causing sooting, lazy or lifting flames, poor efficiency, and potential lockouts. Using the factory-specified orifice restores clean, correctly-rated combustion.
The genuine Goodman OEM orifice carries the exact drill size engineered for this model's manifold pressure and input rating. Generic orifices with even slightly different bores change BTU input and combustion — a safety and efficiency concern. Always match the OEM spud size for natural gas service.
Easy–Moderate (2/5). A gas-line component: shut off gas and power. Loosen the manifold or remove the burner, thread out the old orifice with the correct wrench, and install the new one snugly without overtightening. Restore gas and leak-check every joint with soap solution before firing. Best performed by a qualified technician; verify flame appearance after startup. ~30 minutes.
