The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM replacement designed for the WFD18090S4BXCB gas furnace and other compatible Goodman and Amana furnace models. The orifice (also called a spud) meters the precise volume of natural gas delivered to each burner, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice can cause poor combustion, sooting, delayed ignition, or a furnace that short-cycles on the flame sensor.
Choosing the genuine OEM 10716003 guarantees the exact drill-size bore Goodman engineered for the correct gas flow rate. Generic or universal orifices may have a slightly different bore, altering BTU input and combustion quality. For a safety-critical gas component, we recommend the OEM part to preserve the furnace's factory rating.
Easy (1 of 5). The orifice threads into the manifold and is replaced with a nut driver or wrench. Always shut off gas and power before servicing, and check for leaks with soapy water after reassembly. Gas appliance work should be performed by a qualified HVAC technician where required by local code.
