How to Fix / Troubleshooting
Safety first: If the fan runs continuously for more than 15–20 minutes after cooking, unplug the unit.
- 1. Determine if behavior is normal: Some Beko models keep the fan running briefly after cooking to cool internal components.
- 2. Check for overheating: If the cabinet feels very hot, allow the fan to run. If it never stops, suspect a fault.
- 3. Power reset: Unplug for 10 minutes and reconnect. If the fan starts immediately and runs continuously, the relay or control PCB may be stuck.
- 4. Professional service: Replacement of the control PCB or fan relay is typically required.
