Failed main relay on control board, Open thermal fuse, Door lock or door switch not signaling closed
How to Fix / Troubleshooting
Safety first: Disconnect power before testing internal components.
- Check for error messages: Ensure there is no DOOR or LOCK indication preventing operation.
- Test thermal fuse: Locate the thermal cutoff fuse (often on the top of the oven cavity). Test for continuity; replace if open.
- Door switch: Verify the door switch or latch switch changes state when the door is closed. Replace if faulty.
- Control board: If safety devices are good but the control never sends power to elements, the electronic oven control board is likely defective and should be replaced.
