The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud precision-drilled for the AMVC950704CXAB modulating gas furnace and compatible Goodman/Amana models. The orifice meters the exact volume of natural gas delivered to each burner, setting the flame size and BTU input the furnace was engineered for. An incorrectly sized or worn orifice throws off the air-fuel ratio, causing sooting, poor flames, incomplete combustion, or reduced heating capacity.
OEM vs. Generic: Orifice bore diameter is measured in thousandths of an inch and is matched to burner design, manifold pressure, and BTU input. The genuine OEM 10716003 guarantees the correct bore for safe, efficient combustion. Generic or mis-drilled orifices are a common cause of over- or under-firing — do not substitute an LP orifice or an unverified aftermarket spud.
Install difficulty: Moderate. Requires removing the burner assembly and a properly sized nut driver/wrench; typically 30–45 minutes. Confirm you need the natural-gas (not LP) version. Gas-carrying components should be serviced by a licensed technician, and manifold pressure must be verified after installation. Always shut off gas and power first.
