Report "The oven keeps saying "cavity - size 30" and then says "press start to set" and the then "press 3 to increase" and the "press 6 to decrease". This started yesterday and I don't have a clue what's going on. The top range works but this seems to be the bottom part oven. We also have a heating drawer in the bottom of it and the stove is the glass top kind with dials in the front. I don't know the model # but it was bought from Sears about 4-5 years ago. My name is Linda Paddison and my phone number is 780-986-2084. My computer is downstairs and I'd have to run up to look at it. Can you help? Thanks for your time"
