Possible Causes
Tripped household breaker, blown internal fuse on control board, faulty mains cable, loose terminal block connections
How to Fix / Troubleshooting
Safety first: Ensure the oven is disconnected before opening any covers. Internal fuses are not to be bypassed.
- Check outlet and breaker: Verify that other appliances work on the same outlet and that the breaker has not tripped.
- Inspect mains cable: Check the power cord for cuts or kinks. Replace if damaged.
- Terminal block: Remove the rear terminal cover and ensure all connections are tight and correctly wired.
- Internal fuse: Access the control board and locate any inline or PCB-mounted fuses. Test with a multimeter and replace only with the same type and rating if blown. If the new fuse blows immediately, there is an underlying short that must be diagnosed.
