My oven maybe has any faults!! I always smelt something burning when using it, only first seconds. I examined and scrubbed it, but nothing leftover inside of this oven. Have you come across this problem? Do you know why? The brand of my oven is AEG, and the model number is U31005M, AEG U31005M built under double oven. Do you know why? Please let me know! Thank you!
