The Goodman 10716005 Natural Gas Orifice is the genuine OEM burner spud for AMEC800804CXAA and compatible Amana/Goodman gas furnaces. Threaded into the gas manifold, the orifice meters the precise volume of natural gas delivered to each in-shot burner. The drill size sets the furnace's BTU input, so a correctly sized OEM orifice is critical for proper combustion, efficiency, and safe operation.
The OEM Goodman 10716005 is precision-drilled to the exact orifice size for this furnace's rated input at your gas pressure. An incorrect generic orifice over- or under-fires the furnace, causing sooting, poor efficiency, or overheating. Never substitute an unverified drill size — match the OEM part and gas type (do not use a natural-gas orifice on LP).
Moderate (3/5). Shut off gas and power, remove the burners to access the manifold, thread out the old orifice and thread in the new one, then verify manifold pressure and flame after reassembly.
Gas orifice replacement must be performed by a qualified HVAC technician per local gas codes.
