The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud precision-drilled to meter the exact gas flow required by the WGFM195045S3BAC gas furnace. A correctly sized orifice is critical to safe combustion, proper BTU input, and clean burner ignition — even a small deviation in the drill size changes the flame and can cause sooting, delayed ignition, or lockouts.
OEM orifices are machined and gauged to Goodman's certified drill diameter for this furnace's manifold pressure, guaranteeing the flame characteristics the unit was rated and safety-listed for. Generic orifices can be mislabeled or drilled off-spec, producing an incorrect flame that risks efficiency loss and safety issues. For a combustion component, OEM is strongly recommended.
Difficulty: Moderate. Requires shutting off the gas supply, removing the burner assembly, and threading in the matching orifice with a properly sized wrench, then leak-testing all connections. Because this is a gas-carrying part, we recommend installation by a licensed HVAC professional and a post-install combustion/leak check. Always confirm your local gas type (natural gas vs. LP) before ordering.
