The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM metering component for the WGFM195090S5CAA 95% AFUE modulating gas furnace and other compatible Goodman/Amana high-efficiency models. The orifice (spud) meters the precise volume of natural gas delivered to each burner, setting the correct air-fuel ratio and BTU input. A clogged, corroded, or incorrectly drilled orifice causes poor flame quality, sooting, delayed ignition, and reduced efficiency.
OEM vs. Generic: The genuine Goodman 10716003 is drilled to the exact orifice diameter your furnace's rated input and manifold pressure require. Substituting a generic or wrong-size orifice changes BTU output and can create a dangerous over- or under-fired condition. The OEM part guarantees the correct burn and preserves your equipment warranty. Note: this orifice is drilled for natural gas — do not use it on an LP/propane conversion.
Install difficulty: Moderate. Plan on 20–40 minutes. Shut off gas and power, remove the burner assembly or manifold as needed, unthread the old orifice, and torque the new one snugly without over-tightening. A combustion analysis and manifold-pressure check by a licensed HVAC technician is strongly recommended after replacing any gas-metering component.
