The Goodman 10716003 is a genuine OEM natural gas burner orifice (gas spud) precision-drilled for the GDH80403ANAA gas furnace. The orifice threads into the manifold and meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient, correctly-sized flame. A worn, corroded, or incorrectly-sized orifice causes poor combustion, sooting, delayed ignition, or reduced heat output.
The genuine OEM 10716003 is drilled to the precise diameter matched to your furnace's BTU rating and manifold pressure. Generic orifices are frequently mis-drilled, producing an over- or under-fired burner that wastes fuel and can create dangerous combustion conditions. For a gas-metering part, always use OEM.
Easy (1/5). Shut off gas and power, then unscrew the old orifice from the manifold and thread in the new one — no sealant on the orifice threads. Verify the flame pattern after startup. If you are unsure about gas work, hire a licensed technician.
