I am very dissatisfied with my new induction range. Cooktop is ok, but oven is very, very noisy. Once I turn on - I get high pitched noise. Today I want to use oven warm function, but I had to turn off because of noise. Yesterday I baked my food on 375 F. Oven made noise all the time and also maybe 45 minutes after turning off. This is not 
normal. It bother me too much. I thing this only my oven does it. I have read all reviews and no one has the same problem.
