Awning window only opening slightly before getting stuck

Question

Hi. My issue is the crank is working properly, but the window now only opens slightly then the crank feels like it gets stuck. Forcing the window open past this point by turning feels like it will break something. I am able to close the window, but now cannot open it more than just a crack. Is there a way to fix this problem so the window can open fully and freely as before?

There are two possible explanations for this problem. First, it's possible that you have a worn operator. The way to check this would be to remove your existing operator entirely and then try operating the window manually. If the window works freely, then the problem is most likely the operator and it needs to be replaced.

However, if the window is still hard to operate even without an operator, then the problem could be the the window linkage at the sides of the window.

Try this method to find out were your problem is and get back to me.
