How to Fix Error F20
DIY Fix Power reset and basic check
- Turn off power at the isolator and circuit breaker for at least 15 minutes
- Restore power and check if the F20 code clears
- Ensure the oven’s power connection is secure and no recent surge occurred
Technician Only Inspect and repair control system
- With power disconnected, open the oven’s access panels and inspect the main control PCB for signs of damage such as burnt components or moisture ingress
- Verify sensor connections (temperature sensor, door switches) and wiring integrity
- If no discrete faults are found and the error persists, replace the main control board with the exact Belling part number
Parts needed: Main control PCB, Temperature sensor (if related faults present), Wiring harnesses/connectors
- If the F20 code persists after a power reset
- If you observe physical damage to internal components
- If you are not confident working with mains-voltage appliance internals
