Professionally installed on 6/24 in afternoon.  Used it for dinner that evening, convection bake then broil, worked great.  Noticed the time displayed on the oven around 10:30 that night.  Next morning, display is gone!  Touch the display/control panel nothing.  Can't get service on it for almost a week!  Thank God I had set up the wifi feature the first evening so I can actually use the oven through my phone if I need to.  Not happy.
