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

Safety first: Ensure the oven is cool and power is off before removing the door.

• Clean vents: Check and clean any ventilation slots at the top of the door with a soft brush.
• Remove and clean glass: Following the user manual, remove the door and then the inner glass panels. Clean and dry all glass thoroughly, paying attention to edges and seals.
• Inspect seals: Check foam or silicone seals around the glass. Replace if deteriorated or missing.

Note: Some minor condensation during heating is normal, but persistent moisture between panes indicates seal failure.
