This OEM Goodman/Amana natural gas burner orifice (part #10716005) is a direct-fit replacement for the AMEC800803BNAB gas furnace. The orifice (spud) meters the precise volume of natural gas delivered to each burner, ensuring the correct BTU input, a stable flame, and efficient, safe combustion. A worn, corroded, or incorrectly sized orifice causes lazy flames, delayed ignition, sooting, and poor heating performance.
OEM (recommended): Factory-drilled to the exact bore size specified for this furnace, guaranteeing correct gas metering and safe combustion. Generic: Lower cost, but drill tolerances vary and an incorrect bore can over- or under-fire the burner. For a gas-metering component, OEM is strongly advised.
Moderate. Requires shutting off the gas supply, removing the burner assembly, and swapping the orifice. Best performed by a licensed HVAC technician; verify manifold pressure after installation.
