The genuine Goodman 10716005 Natural Gas Burner Orifice is a factory OEM replacement engineered for the AMVC800803BNAB variable-speed, two-stage 80% AFUE gas furnace. This precision-drilled orifice (spud) meters the exact volume of natural gas delivered to the burner, ensuring a clean, stable flame and rated BTU output. A worn, cross-threaded, or incorrectly sized orifice causes lazy or roaring flames, sooting, and efficiency loss — restoring the correct part brings combustion back to factory spec.
Because an orifice controls the gas-air mixture, drill-size accuracy is safety-critical. Our OEM Goodman 10716005 guarantees the exact factory bore for your model, while a generic universal spud may run rich or lean and require re-drilling. For gas components, we recommend OEM.
Moderate — requires shutting off gas, removing the burner assembly, and leak-checking after reinstall. Professional installation by a licensed HVAC technician is strongly recommended for any gas-carrying part.
