The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component engineered for the GMH950453BXAC gas furnace and compatible Goodman/Amana models. This precision-drilled orifice (spud) meters the correct volume of natural gas to the burner, ensuring a clean, efficient flame and proper BTU output. A worn, corroded, or incorrectly sized orifice causes poor combustion, sooting, or lockout faults — replacing with the exact OEM part restores factory-rated performance.
OEM orifices are drilled to Goodman's exact factory bore diameter, guaranteeing correct gas flow and BTU rating. Generic or universal orifices may vary in bore size, risking over- or under-firing, incomplete combustion, and warranty complications. For a safety-critical gas component, OEM is strongly recommended.
Moderate — requires shutting off gas, removing the burner assembly, and swapping the orifice with proper thread sealing. Gas connections should be leak-tested. Recommended for HVAC professionals or experienced DIYers.
