The Goodman 10716003 Natural Gas Orifice is the genuine OEM burner spud that meters gas flow into each burner of the GCH950703BXAD gas furnace. The precisely machined orifice bore sets the firing rate and, together with the burner, establishes proper flame quality and BTU input. Using the correct orifice is essential for safe, efficient combustion and to keep the furnace within its rated capacity.
Orifice sizing is not something to approximate. The OEM 10716003 carries the exact drill number Goodman engineered for this manifold pressure and altitude range, ensuring a clean blue flame and correct input. An incorrect generic orifice can cause sooting, delayed ignition, or overfiring. Always match OEM for gas-metering components.
Moderate (3/5). Recommended for a licensed technician: shut off gas and power, remove the manifold or burner, thread the new orifice to spec, and verify flame appearance plus manifold pressure with a manometer after startup.
