Hello, I have such a problem, the stove blower does not close or close, I have to set the screw with my finger on the open and leave it like that, because when the load is too heavy, the screw does not rise (the blower has no force), and when it is too small, the screw does not it returns .. I tried to tighten the nuts, but the effect was that, for example, the blower slightly lifted the bolt without return.
