Possible Causes
Weak safety thermostat, Blocked cooling vents, Failing cooling fan, Oven installed too tightly in cabinet
How to Fix / Troubleshooting
Safety first: Turn off power and allow the oven to cool before inspection.
Step-by-step checks:
- 1. Check ventilation: Ensure the oven has the clearances specified in the Zanussi installation guide. Improve airflow if cabinets are too tight.
- 2. Inspect cooling fan: Confirm the tangential fan runs whenever the oven is hot. Replace if slow, noisy, or intermittent.
- 3. Test safety thermostat: If the thermostat trips at relatively low temperatures, replace it with a genuine Zanussi part.
- 4. Clean vents: Remove dust and grease from ventilation slots and fan intakes.
Warning: Do not bypass a tripping thermostat; it is indicating an overheating condition.
