How to Fix / Troubleshooting

Safety first: Disconnect power after a trip and allow the oven to cool before inspection.

Steps to check:

Run the oven briefly under supervision until just before it would normally trip (if safe to do so), then disconnect and inspect for hot spots or burning smells.
Check the mains terminal block for discoloration or melting; replace if overheated.
Inspect all elements and their ceramic insulators for cracks or carbon tracking.
Test elements for earth leakage when cold and, if possible, when warm (technician with proper equipment).
Verify that the cooling fan operates correctly to prevent overheating of wiring and PCB.

Warning: Intermittent trips can be difficult to diagnose; professional testing equipment may be required.

Oven trips the breaker after some minutes of operation, not immediately.
