Oven glass door is fogging up excessively or condensation forms between glass panes.

Safety First: Ensure the oven is cool before working on the door. Glass edges can be sharp; wear cut-resistant gloves.

• Normal condensation: Some fogging on the inner surface during preheat is normal and should clear as the oven heats.
• Between panes: If moisture is between glass panes, the door must be disassembled. Remove the door, lay it on a padded surface, and remove screws holding the inner and outer panels.
• Clean and dry: Separate the glass panes, clean with glass cleaner, and allow to dry completely.
• Inspect seals and vents: Replace any damaged glass gaskets and ensure door vents are not blocked. Reassemble the door securely.
