My microwave 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 discount shopping microwave. Have you come across this problem? Do you know why? The brand of my microwave is Bosch , and the model number is
HBC84K521B , Bosch HBC84K521B Compact Built-in Oven and Microwave. Do you know why? Please let me know! Thank you!
