The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the AMEC801005CNAB gas furnace and compatible Goodman/Amana models. The orifice meters the precise volume of natural gas delivered to each in-shot burner, setting the furnace's input rate and flame quality. A clogged, damaged, or incorrectly sized orifice causes weak or oversized flames, sooting, delayed ignition, and inefficient heating. Installing the factory orifice restores the correct, safe gas metering.
Orifice drill size directly controls gas input and combustion safety. The genuine OEM orifice is drilled to the exact size Goodman specifies for this furnace's rated input on natural gas. Generic or mis-sized orifices can over- or under-fire the burners and create CO or sooting risk. For any gas-metering part, use only the correct OEM orifice — and never substitute an LP orifice on a natural-gas furnace.
Rating: Moderate. Shut off gas and power, remove the burner or access the manifold, and thread the orifice into place with a proper wrench — do not over-tighten. Best performed by an experienced DIYer or licensed technician; always leak-test the connection and verify flame quality after installation.
