The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner metering component engineered for the GMH951155DXAD gas furnace and compatible Goodman/Amana models. The orifice threads into the manifold and precisely meters the flow of natural gas into each burner, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice causes poor combustion, sooting, or nuisance lockouts — this exact-spec replacement restores factory performance.
Genuine Goodman orifices are drilled and gauged to the manufacturer's exact BTU rating for your model. Generic or misdrilled orifices can over- or under-fire the burner, wasting fuel and risking incomplete combustion. For a safety-critical gas component, the OEM part guarantees the correct flame characteristics your furnace was certified for.
A basic repair for a licensed HVAC technician — shut off the gas, remove the manifold or burner assembly, unthread the old orifice, and install the new one with proper thread sealant rated for gas. Always leak-check and verify manifold pressure after replacement. Gas work should be performed by a qualified professional.
