Possible Causes
Partially failed heating element (hairline crack), Faulty temperature sensor reading too high, Door seal leaking heat, Convection fan not running in fan modes
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the oven to cool before internal inspection.
- Check elements: Visually inspect top, bottom, and circular elements for cracks or hot spots. Test each for correct resistance with a multimeter.
- Verify fan operation: In fan-forced mode, ensure the convection fan runs. If not, see the convection fan fault procedure.
- Inspect door seal: Check the gasket around the door for gaps, tears, or compression. Replace if it does not seal evenly.
- Test temperature: Use an oven thermometer to compare actual temperature to the set temperature. A large discrepancy may indicate a faulty sensor or calibration issue.
- Replace faulty parts: Replace any weak element, damaged door seal, or inaccurate temperature sensor with DeLonghi-approved parts.
