Customer Questions and Answers for Waveguide Cover (Microwave) by Ge

This microwave waveguide cover shields the waveguide opening from grease and moisture while allowing microwave energy to enter the cavity. Replace a burned, cracked, or missing cover to stop arcing and help protect internal components.

• Shields the waveguide port from food splatter, steam, and debris
• Helps prevent arcing/sparking when the original cover is scorched or contaminated
• Maintains a clear path for microwave energy to support proper cooking performance
• Common signs: visible burns or charring, crackling/sparking from the wall opening, staining or food behind the cover

• Disconnect power before servicing; microwaves can retain high voltage—do not open the cabinet
• From inside the oven cavity, remove the screw or release the tabs securing the old cover; clean the surrounding area
• Position the new cover flush over the opening and secure it using the existing fastener(s)
• Never operate the microwave without the waveguide cover installed
