Possible Causes
Blocked ventilation around built-in oven, failed cooling fan, faulty overheat thermostat, degraded cavity insulation
How to Fix / Troubleshooting
Safety first: Allow the oven to cool fully before further testing. Do not bypass safety thermostats.
- Check installation: Ensure the oven has the clearances specified by De Dietrich. Remove any items blocking front or rear vents.
- Verify cooling fan: Confirm that the top cooling fan runs during and after cooking. If not, test and replace the cooling fan assembly as needed.
- Inspect overheat thermostat: Locate the overheat thermostat on the top or rear of the cavity. Test for continuity at room temperature. If open and non-resettable, replace it.
- Clean vents: Remove dust and grease from ventilation channels and fan blades.
- Persistent errors: If the oven still overheats despite proper ventilation and a working fan, internal insulation or control calibration may be compromised; professional diagnosis is recommended.
