The Goodman 10716005 Natural Gas Burner Orifice is a genuine OEM metering jet (spud) for the Amana AMES921004CNAA gas furnace. The orifice threads into the manifold and precisely meters the volume of natural gas delivered to each burner, setting the firing rate and ensuring a clean, correctly-sized flame. A worn, corroded, or incorrectly-sized orifice causes poor combustion, sooting, delayed ignition, or a furnace that won't reach its rated BTU output.
This genuine OEM Goodman orifice is drilled to the exact factory bore for your furnace's rated input and altitude spec. Because orifice sizing directly controls the fuel-air mixture, we recommend OEM only — an incorrect bore can create dangerous over- or under-firing. Always match the orifice to your furnace's rating plate and fuel type.
Moderate (3 of 5). Roughly 20–40 minutes and a gas-safe job. Shut off gas and power, remove the burner assembly to access the manifold, unthread the old orifice, and install the new one to proper torque. A leak check with soap solution afterward is mandatory. Because this involves the gas train, we recommend a licensed HVAC professional.
