Possible Causes

Failed inner door glass seal, Blocked vent channels, Previous door disassembly not sealed correctly

How to Fix / Troubleshooting

Safety first: Allow the oven and door to cool completely before working on the glass assembly.

  • 1. Check exterior: Some condensation on the inner surface during cooking can be normal. Persistent moisture between panes indicates a seal issue.
  • 2. Inspect door vents: Ensure that the door vent slots are not blocked by foil or grease buildup. Clean gently.
  • 3. Disassemble door: Remove the door and carefully disassemble according to La Cornue instructions, noting the order of glass panes and seals.
  • 4. Replace seals or glass: Install new door glass seals or a complete glass pack if the original seals are degraded. Reassemble tightly to prevent air leaks.
