Possible Causes
Shorted heating element, damaged wiring touching chassis, faulty mains filter, moisture inside elements
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset the breaker; there is a risk of electric shock or fire. Isolate the oven.
- Identify mode causing trip: Try different functions one at a time (with caution). If only grill trips, suspect grill element; if fan mode trips, suspect fan element.
- Visual inspection: With power off, inspect elements and wiring for burn marks or contact with metal chassis.
- Insulation test (professional): Use a megohmmeter to test elements to earth. Replace any element with low insulation resistance.
Because this involves live circuits and safety, professional diagnosis is strongly recommended.
