Possible Causes
Failed cabinet temperature thermostat, Blocked cooling airflow around oven, Incorrect installation without ventilation gaps, Faulty cooling fan
How to Fix / Troubleshooting
Safety first: Switch off power and allow the oven to cool completely.
- Verify installation: Check that the oven has the required clearance from surrounding cabinetry and that ventilation slots are not blocked.
- Inspect cabinet thermostat: Locate the cabinet thermostat (often mounted on the top or side of the oven casing). Check for loose wires or signs of overheating.
- Reset thermostat (if resettable): Some thermostats have a small reset button. Press gently to reset.
- Check cooling fan: Ensure the cooling fan runs when the oven heats. If not, test and replace the cooling fan motor.
- Replace thermostat: If E20 recurs and the thermostat does not reset or tests open-circuit at room temperature, replace it with a compatible Russell Hobbs cabinet thermostat.
