The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) designed for the WFD18070S3AXCB furnace. The orifice threads into the manifold and meters the precise volume of natural gas delivered to each burner. Its factory-drilled bore is matched to the furnace's rated BTU input and gas type, ensuring clean, efficient combustion and a properly shaped flame.
Orifice bore size directly controls the gas input rate. The OEM 10716003 is drilled to Goodman's exact specification for this model, so combustion stays within factory tolerances. Generic orifices with an incorrect drill size can cause under-firing, over-firing, sooting, or unsafe combustion — never substitute an unverified bore diameter on a gas appliance.
Easy to Moderate (2/5). The orifice unscrews from the manifold with a nut driver or wrench, but the work is on a live gas line. Shut off the gas supply and power, replace the orifice, and always leak-test connections with soap solution before relighting. Gas component work should be performed by a licensed HVAC technician where required by local code.
