The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner orifice (spud) that meters the flow of natural gas into the burner on the AMEC960803BNAC gas furnace. The precisely drilled orifice bore sets the gas input rate, so it is critical to combustion efficiency, proper flame characteristics, and safe operation.
The OEM 10716005 orifice is drilled to the exact bore diameter specified for this furnace's rated input. Because orifice size directly controls the gas rate, using a mismatched or generic spud can cause over- or under-firing, sooting, delayed ignition, or unsafe combustion. This is a safety-critical part where the correct OEM orifice is strongly recommended.
Moderate (3/5) — professional recommended. Requires shutting off gas, removing the manifold or burner, and swapping the orifice, then verifying manifold pressure and firing rate. Gas-fired equipment should be serviced by a qualified HVAC technician per local code. Always shut off gas and power before servicing.
