The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the WGFM295045V3BAB gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the furnace's BTU input and ensuring clean, efficient combustion. A worn, corroded, or incorrectly drilled orifice causes poor flame quality, sooting, or improper firing rate.
The OEM Goodman 10716003 is drilled to the exact orifice size for this furnace's rated input and manifold pressure. Using a generic or wrong-size orifice changes the firing rate and can create unsafe over-firing or incomplete combustion. Because it directly controls the gas/air mixture, only the correct OEM orifice should be installed.
Moderate — requires removing the burner assembly and a proper wrench to seat the orifice without cross-threading. Combustion should be verified after service. We recommend a licensed HVAC technician. Always shut off gas and power first.
