The Goodman 10716003 Natural Gas Orifice is the genuine OEM main burner spud for the AMVC950453BXAE 96% AFUE two-stage variable-speed gas furnace. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, setting the flame size and total BTU input for safe, efficient combustion.
Orifices can become clogged with debris, corroded, or damaged during service. A worn or wrong-size orifice causes poor flames, sooting, delayed ignition, or lockouts. Using the factory-specified orifice keeps the furnace firing at its rated input and protects the heat exchanger.
OEM vs. Generic: Orifice bore diameter is critical — even a few thousandths of an inch changes the gas flow and flame. Our OEM Goodman orifice is drilled to the manufacturer's exact specification for this model. Generic spuds may look identical but can over- or under-fire the furnace, creating a safety and efficiency risk. Always match OEM for gas-metering parts.
Installation difficulty: Moderate (3/5). Shut off gas and power, unthread the old orifice from the manifold with the correct wrench, install the new orifice hand-tight plus a snug turn, then leak-test with soap solution and verify the flame. Recommended for experienced DIYers or an HVAC technician.
