my kenmore electric range model # 790.9031 is giving me lots of problem the main two,it burns stuff on the range that is impossible to remove even with brillo pads, it takes the oven over 15 mins. to pre-heat. Also the stove top and front of the stove gets so hot it will burn you, and when things are cooking on the stove top it make real loud noises like the metal is warping. I am afraid to let my grandchildren cook because of how hot the stove gets they will get burned.
