I bought this oven less that an year and a half ago. Everything was fine and worked well for a while. But four months after the warranty expired so did my oven. It just quit working. I  have tried to figure out how to diagnose my problem so I could repair my oven. It has fancy electronic diagnostic codes. However, all they will tell me to do is call a repair technician. I am not interested in paying a costly repair man sixteen months after buying a new stove/oven. I saw several other reviews with this same complaint. I do not recommend this product.
