The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the Amana/Goodman AMH80905CXCA 80% AFUE gas furnace. This precision-drilled brass orifice threads into the gas manifold and meters the exact volume of natural gas delivered to each in-shot burner. Correct orifice sizing is essential for proper input BTU, clean combustion, and safe operation — a missing, damaged, or incorrectly drilled orifice will produce an improper flame.
The genuine 10716003 is drilled to Goodman's exact orifice number for this furnace's rated input. Using a generic or mis-drilled orifice changes gas flow, causing under-firing, over-firing, sooting, or unsafe combustion. Never substitute an unverified orifice — always match the OEM part or the factory drill chart.
Rated 2 of 5. The orifice threads out of the manifold with a nut driver or wrench and the replacement threads back in — but exact orifice sizing must be confirmed for your specific model and altitude. If converting fuel types, use the manufacturer's conversion kit. Shut off gas and power before servicing.
Genuine OEM Goodman part. Verify orifice size for your model and installation altitude before ordering.
