The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the WGFD28090V5CXAA gas furnace and compatible Goodman/Amana models. The orifice meters the precise gas flow into each in-shot burner, controlling BTU input and ensuring a clean, correctly proportioned flame.
Orifice drill size directly determines firing rate and combustion quality. A generic orifice with an incorrect bore can over-fire (safety and efficiency risk) or under-fire (poor heat output). This OEM spud is precision-drilled to Goodman's factory specification for this model, guaranteeing correct input.
Easy — Shut off the gas supply, remove the manifold or unthread the individual orifice, and install the replacement with the matching thread. Verify no gas leaks and confirm proper flame appearance after service. Do not mix natural gas and LP orifices — use the correct fuel-specific part.
