Mymanual French door counter top oven worked well for a little while but the thermostat seems to have failed and this oven doesn't seem to have any kind of shut down for thermal fun away. The oven got so hot my inflated thermometer read 300° on the top. Keep in mind my oven was set to bake and 200°.  Very well could have but t my house down if I wouldn't have smelt the smoke and shut it down myself.
