Possible Causes

How to Fix / Troubleshooting
Safety first: Turn off power at the breaker immediately. Do not use the oven until the issue is resolved.
- Check elements:
- Visually inspect bake and broil elements for visible breaks, blisters, or arcing marks.
- Inspect PCB:
- Remove the rear panel and inspect the main relay board for burnt relays or traces.
- Test elements (advanced):
- Disconnect one wire from each element and measure resistance; compare to service specs.
- Replace any element that is shorted or significantly out of spec.
- Replace main PCB: If relays are stuck or the board is burnt, replace the main relay control board.
- Due to fire risk, professional service is strongly recommended.
