The Goodman 11072202 Burner Orifice Shield is a genuine OEM component for the WGGE4348A070MAB gas furnace and compatible Goodman and Amana models. The orifice shield guards the burner orifice from cross-currents and downdraft, helping deliver a stable, well-defined flame at light-off and steady state. A properly seated shield promotes clean ignition carry-over between burners and consistent combustion.
OEM vs. Generic: The genuine Goodman shield matches the exact geometry and burner spacing of your furnace, so airflow around the orifice behaves as designed. Generic or bent aftermarket shields can disrupt the flame pattern, causing rough ignition, flame sensor dropout, or noisy operation. For a combustion-critical part we recommend OEM.
Install difficulty: Easy (2/5). The shield mounts at the burner/orifice assembly and is typically retained by the burner rack or a small fastener. Turn off gas and electrical power before servicing. Inspect burners for rust or scale while you have the assembly open, and verify a crisp blue flame after restart. If you are unsure about combustion setup, have a licensed HVAC technician confirm proper operation.
