The Goodman 10716005 Natural Gas Burner Orifice is a genuine OEM component that meters the flow of natural gas into the burner of your AMVC80803BXBD modulating gas furnace. Each orifice (also called a spud) is precision-drilled to a specific diameter so the furnace delivers its rated BTU input at the correct manifold pressure. A worn, corroded, or incorrectly sized orifice throws off the air-to-gas ratio, producing sooty flames, delayed ignition, or reduced heating capacity.
Orifice sizing is safety-critical. This genuine OEM Goodman orifice is drilled to the exact bore your furnace is certified for. Generic orifices may deviate in bore diameter, over- or under-firing the burner and risking incomplete combustion and elevated CO. OEM guarantees the correct BTU input and clean, stable flames.
Rating: Easy (2/5). The orifice threads into the manifold and is removed with a nut driver or wrench. Straightforward mechanically, but gas work should be verified for leaks with a licensed technician. Shut off gas and power before servicing.
