The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud that meters the precise flow of natural gas into the in-shot burners of your AMVC80803BNBD furnace. The orifice bore size sets the gas input rate (BTU) for each burner, making it critical to safe, efficient combustion. A damaged, corroded, or incorrectly sized orifice causes under- or over-firing, sooting, and poor efficiency.
Orifice sizing is not universal — the bore diameter is engineered to the furnace's rated input and local gas pressure. This genuine Goodman orifice is factory-drilled to the correct size and thread, guaranteeing proper firing rate. A generic or mis-sized orifice can create a hazardous rich or lean flame and void warranty coverage.
Moderate — Threads into the gas manifold; requires removing the burner assembly and leak-testing the connection afterward. Best performed by a licensed HVAC technician. Shut off gas and power before service. Typical install time: 20–30 minutes.
