We had our oven installed 20 days ago.  Before I ever used it, the oven and the oven light mysteriously came on during the night .  We are not able to turn it off.  We took out extra insurance but when we called the service department for help, we were informed that it would be a week before anyone could come service us.  So we are now unable to use our new oven.  We cannot set or change the temperature.  So our new oven is on and running 24/7!!
