Range does not operate as described in the owner's Manuel as described on page 23 under "Setting Bake." Specifically the range beeps prior to reaching set temperature which is at variance to what the manuel indicates. Three technicians have come out and verified that it doesn't work according to the manual but has said it is working as designed. Which doesn't make sense as the design and the manuel should match up., but they don't. Results - if you put your food in when the range beeps and follow the recipe as to the timing the food comes out undercooked. Resolution - either provide a range that works properly or provide a full refund so that I may go purchase a range that works as described.
