The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the AMVC80805CNBC 80% AFUE variable-speed gas furnace. The orifice meters the exact volume of natural gas into each in-shot burner, setting the furnace's firing rate and BTU input. A worn, clogged, or incorrectly-sized orifice causes poor flame, sooting, or an out-of-spec heat rate.
Orifice drill size is what determines safe, correct combustion. This OEM Goodman/Amana orifice is drilled to the factory specification for this furnace at nameplate manifold pressure. Generic or mis-sized orifices can over- or under-fire the unit — a safety and efficiency risk. Match OEM exactly.
Moderate (3/5). Requires shutting off gas, removing the burner/manifold, and threading in the new orifice without cross-threading. Verify manifold pressure and flame after install; a manometer is recommended. Best for experienced DIYers or a licensed technician.
