Possible Causes

Failed cooling fan, Damaged inner door glass or insulation, Missing or damaged door seal

How to Fix / Troubleshooting

Safety first: Be cautious of hot surfaces. Allow the oven to cool before disassembling the door.

  • Check cooling fan: During operation, listen for the top cooling fan. If it does not run, test and replace the cooling fan motor if faulty.
  • Inspect door seal: Ensure the door gasket is intact and sealing properly. Replace if worn.
  • Check door glass: If the inner glass is cracked or missing, heat transfer to the outer glass increases. Replace damaged inner door glass and ensure all insulation panels are correctly positioned.

If the cooling system and door components are intact but the door is still excessively hot, consult a technician to verify installation and airflow.
