How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Disconnect the appliance and investigate before reuse.
- Visual inspection: Remove rear panel and inspect elements and wiring for burn marks or melted insulation.
- Insulation test: With a megohmmeter (if available), test each element from terminal to chassis. Low insulation resistance indicates a leaking element that must be replaced.
- Dry moisture: If the oven was recently cleaned with water or steam, allow it to dry thoroughly for 24 hours and retest.
- Check terminal block: Inspect the mains terminal block for signs of overheating or loose connections. Replace if damaged.
- Replace faulty element: Replace any element that shows visible damage or poor insulation.
