The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the ACV90905DXBB furnace. This precision-drilled brass orifice meters the exact volume of natural gas into each burner, establishing the correct air-fuel mixture for clean, efficient combustion. A worn, corroded, or incorrectly-sized orifice causes sooting, poor flame, and reduced heating capacity — making the factory-spec replacement essential.
Orifice bore size determines the firing rate (BTU) of the furnace. The genuine OEM 10716003 is drilled to Goodman's exact specification for this model and elevation; a generic or mis-sized orifice can over- or under-fire the furnace and produce dangerous carbon monoxide. Always use the OEM-matched part for gas components.
Moderate — gas work, caution required. Shut off the gas supply and power before service. Removing and reseating an orifice requires the correct wrench and a leak check afterward. We recommend a licensed HVAC professional for any gas-side repair.
