The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the Amana / Goodman AMEH800603BNAA gas furnace. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's rated BTU input. Using the correct orifice size is critical: an oversized bore over-fires the heat exchanger while an undersized bore starves the flame, causing sooting, poor combustion, and nuisance lockouts.
The OEM 10716005 is drilled to Goodman's factory specification for guaranteed input rating and clean, quiet combustion. Generic orifices are available at a lower price and are dimensionally compatible, but always verify the drill size stamp matches your unit's rating plate before firing.
Install difficulty: Easy to Moderate. Requires removing the burner assembly and threading the orifice into the manifold. Shut off gas at the valve, use a proper wrench to avoid cross-threading, and leak-check with soap solution after reassembly. Estimated time: 20–30 minutes.
