How to Fix / Troubleshooting
Safety: Do not repeatedly reset a tripping breaker. Isolate the cooker and investigate before reuse.
- Identify mode causing trip: Note whether the trip occurs in grill, main oven, or fan mode. This helps locate the faulty circuit.
- Insulation test (professional): Ideally, use an insulation resistance tester to check elements to earth. Replace any element with low insulation resistance.
- Visual inspection: Check all wiring for melted insulation or contact with sharp metal edges. Repair and secure as needed.
- Dry moisture: If the fault appeared after cleaning or a spill, allow the oven to dry for 24–48 hours with doors open (power off). If tripping persists, components must be tested and replaced.
