The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) for AMES960403ANAA gas furnaces. This precision-drilled brass fitting threads into the manifold and meters the exact volume of natural gas delivered to each burner. Correct orifice sizing is critical — it governs the BTU input, flame shape, and combustion efficiency of the furnace. An incorrectly drilled or worn orifice can cause sooting, delayed ignition, or an over/under-fired burner.
The OEM Goodman orifice is drilled to the precise diameter matched to this furnace's manifold pressure and BTU rating. Generic orifices are sold in nominal drill sizes that may not match the factory calibration, risking incorrect firing rate and poor combustion. For safe, efficient heat, use the OEM part.
Moderate. Shut off gas and power, remove the burner assembly, and unthread the orifice with a nut driver or open-end wrench. Verify the drill size stamped on the spud matches before reassembly, then leak-test all connections. A combustion analyzer check is recommended after service.
