Purchased this oven to replace my 12 year old GE double oven. The bottom oven worked fine but the upper oven did not. There was flaw with either the button switch that senses the door closed or the main board itself.  The dealer was fantastic in dealing with this and provided a technician and got parts on order right away. They will be installed this week.  However,  this review isn't about my dealer but the poor initial quality of the oven.
