Purchased in October, seemed great. Three months later, the range top doesn't cook evenly. I have to put food to the middle of flat-bottomed, induction ready, cookware.. Then, last night, while baking at 375, the fan started whirring like crazy and then the beeping started. We turned the timer off, it kept beeping. We turned the oven off, It kept on beeping! We literally could not turn it off. We left it unplugged for 5 minutes and then plugged it back in. No one answers the call line on the weekends, so I don't know what else to do yet about this issue. Also, the fan in general is really loud on this oven. Our dining room is in the kitchen and we often have a hard time talking over the fan!
