The Goodman 10716003 natural gas burner orifice is a precision-machined OEM component for the WGFD293070V4CAA gas furnace. The orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient flame and proper BTU output. A worn, corroded, or incorrectly sized orifice can cause sooting, delayed ignition, or unsafe combustion — making the factory-spec orifice a critical safety and efficiency part.
Orifice diameter is drilled to a precise factory dimension matched to the furnace's rated input. Generic orifices may be over- or under-drilled, causing incorrect gas flow, poor flame quality, and potential CO risk. The genuine OEM 10716003 guarantees the correct orifice size for safe, efficient combustion.
Moderate (2/5). Requires removing the burner assembly and a wrench to swap the orifice. Shut off gas and power first, and verify no leaks with soapy water on restart. Recommended for experienced DIYers or a licensed technician.
