Possible Causes
Element shorted to earth, Damaged wiring insulation touching chassis, Faulty oven lamp holder, Moisture ingress into electrical components
How to Fix / Troubleshooting
Safety: Do not repeatedly reset a tripping breaker. Isolate the oven and only proceed if you are competent with electrical testing.
- Visual inspection: Remove rear and top covers. Look for burnt wiring, melted insulation, or signs of water ingress around terminals.
- Insulation test of elements: Disconnect each heating element and test resistance between each terminal and earth. Any low resistance indicates earth leakage; replace the element.
- Check lamp holder: Remove the oven lamp and inspect the holder for cracks or carbon tracking that could cause shorts.
- Dry out moisture: If there are signs of condensation or water, allow the oven to dry thoroughly and address any source of leaks.
