The Goodman 10716005 natural gas burner orifice is a genuine OEM component for the GDS90805D2AA gas furnace. This precision-drilled brass orifice (spud) meters the exact volume of natural gas delivered to each burner, ensuring correct BTU input, clean combustion, and safe, efficient furnace operation.
The genuine Goodman orifice is drilled to the exact bore diameter specified for this furnace's manifold pressure and burner design. Even a fractional change in orifice size alters gas flow, causing sooting, delayed ignition, or an over-fired heat exchanger. Generic orifices vary in bore tolerance — for a gas-fired appliance, the OEM part protects both efficiency and safety.
Moderate (2/5). Requires shutting off gas, removing the burner assembly, and threading the orifice into the manifold. Best performed by an HVAC technician. Verify natural gas (not LP) before installing and leak-check all connections.
