The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud built for the GCV90905DXBA gas furnace. Each orifice is precision-drilled to deliver the exact gas flow the burner assembly requires, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice causes lazy flames, sooting, and lockouts.
Orifice bore diameter directly controls firing rate, so precision matters. The OEM 10716003 is drilled to factory spec for safe, efficient combustion. Generic or re-drilled orifices risk over- or under-firing, which can trip safeties or produce carbon monoxide. Always choose OEM for gas-carrying parts.
Moderate — requires shutting off gas, removing the burner assembly, and threading the orifice with a nut driver. Best performed by an HVAC technician; verify no gas leaks after install.
