This is just the latest in the saga of this sad piece of crap. This will be the sixth (I think) service call. During the convection cook cycle the unit went belly up. No reboot. DOA. Prediction: unit will have to come down for repair and only one serviceman will be sent requiring a reschedule which will result in the same thing. On the third visit I will be told I must remove new stove underneath first. This will be difficult for me to take and I will remove the microwave by myself and throw it into the front yard in front of them. Never will purchase appliance from Sears again. I hate Kenmore problems.
