The Goodman 10716003 is a genuine OEM natural gas burner orifice (also called a spud) sized for the WGGE4336A045MAB gas furnace and compatible Goodman/Amana equipment. The orifice threads into the manifold and meters the precise volume of natural gas delivered to each burner. Its factory-drilled bore is matched to the furnace's rated input BTU and gas type, so replacing a worn, corroded, or incorrectly-drilled orifice restores a clean, correctly-sized flame.
Orifice drill diameter directly controls the furnace's firing rate. The OEM 10716003 is drilled to Goodman's exact specification for this model, guaranteeing correct BTU input and safe combustion. Generic orifices can vary in bore size, leading to over-firing, sooting, or incomplete combustion. For gas-carrying components, always use the OEM-spec orifice.
Moderate (3/5). Requires shutting off gas, removing the manifold or burner assembly, and threading in the new orifice. A gas leak check and combustion verification should follow. Recommended for experienced DIYers or a licensed technician.
