Hi,
It's possible the thermostat is in working order, there may be an issue with your oven's ventilation. Poor ventilation can cause the heat to build up to the point that the oven overheats and causes the thermostat to trip, again cutting out your oven in the process

If still have the issue
And have warranty on oven
Try contacting support
