Possible Causes

Failed cooling fan, Blocked ventilation, Damaged door gasket, Misaligned door directing heat toward controls

How to Fix / Troubleshooting

Safety first: If controls are too hot to touch comfortably, stop using the oven until the cause is identified.

  • 1. Check gasket and door alignment: Inspect the door seal and hinge alignment. Replace the gasket or adjust hinges if heat is escaping toward the control panel.
  • 2. Verify cooling fan operation: Ensure the top cooling fan runs during and after baking. Replace the fan motor if inoperative.
  • 3. Clear vents: Make sure upper and lower vents are not blocked by cabinetry or objects.
  • 4. Test at lower temperature: Run the oven at a moderate temperature and monitor control temperature. If still excessive, consult a technician to evaluate insulation and airflow.
