Possible Causes

Failed cooling fan, missing or misfitted inner glass panel, damaged door seal, blocked ventilation slots

How to Fix / Troubleshooting

Safety first: Avoid touching the glass with bare skin if it is excessively hot. Allow the oven to cool before inspection.

  • Check cooling fan: Ensure the top cooling fan runs during operation. If not, test and replace the fan assembly.
  • Inspect door glass: Verify that all glass panels are present and correctly seated. If inner glass is cracked or missing, replace the door glass set.
  • Check seal and vents: Ensure the door gasket is intact and that front/top vents are not blocked.
  • Service if necessary: If the door still overheats, internal insulation or airflow may be compromised and should be evaluated by a technician.
