The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component engineered for the AMH81155CNAA gas furnace and other compatible Goodman/Amana 80% AFUE models. This precision-drilled brass spud meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient flame and the correct rated BTU input. A worn, corroded, or incorrectly drilled orifice causes poor combustion, sooting, delayed ignition, or nuisance lockouts — replacing it with the factory part restores safe, reliable heating.
Generic orifices are often drilled to a nominal size and may not match your furnace's exact gas-input rating, risking over- or under-firing. This authentic OEM orifice is calibrated to Goodman's original combustion spec, protecting efficiency, warranty coverage, and safe operation.
Moderate — requires removing the burner assembly and gas manifold. Recommended for a qualified HVAC technician; a combustion check should follow any burner service.
