Oven door glass is fogging up or moisture is trapped between glass panes.

Safety First: Allow the oven and door to cool completely before disassembly. Glass edges can be sharp.

• Drying cycle: Sometimes repeated normal baking cycles will gradually dry minor condensation. Ensure vents are not blocked.
• Inspect door assembly: Remove the door and disassemble the inner and outer panels according to the service manual. Check gaskets and seals around the glass panes.
• Clean and reseal: Clean glass surfaces and replace any damaged gaskets or seals. Tighten door trim screws evenly to ensure a good seal.
• Replace door glass: If glass is etched or seals are not serviceable, replace the affected glass assembly.
