This genuine Goodman 10716003 natural gas burner orifice (spud) is a direct-fit replacement for the WGGE4324A045MAB gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the furnace's BTU input and flame quality. A damaged, corroded, or incorrectly sized orifice causes poor flame, sooting, delayed ignition, or improper heat output. Installing the correct OEM spud restores clean, efficient combustion.
Orifice drill size directly determines fuel input and safe, efficient combustion. The genuine Goodman 10716003 is drilled to the exact factory diameter for this furnace's natural gas rating. Generic or mislabeled orifices can over- or under-fire the burner, creating sooting, carbon monoxide risk, or reduced heat. On a fuel-metering part, OEM precision is essential.
Moderate (3/5). Shut off gas and power, remove the burner assembly or manifold as needed, thread in the new orifice, and reassemble. Because this affects gas input and combustion safety, a licensed technician should verify manifold pressure and flame after installation.
