Possible Causes
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a breaker that trips; this indicates a dangerous fault. Turn off power and leave it off until the issue is found.
Inspect elements and wiring:
- Remove power and access the bake and grill elements from inside and rear.
- Look for spots where the element sheath has cracked and touches the oven cavity.
- Inspect wiring harnesses for melted insulation or contact with sharp metal edges.
Test components:
- Disconnect each suspect component (elements, fan motors) one at a time and test for continuity to ground with a multimeter.
- Replace any component that shows a short to chassis.
If no component is shorted, the main control board may have an internal short and should be replaced.
