Thanks for posting, Jennifer. Looks like the gear bore has come out, which means the entire operator will need to be replaced. Its gears have completely stripped out, and that cannot be repaired. Check out our 39-155 and 39-156 and let me know if these match your existing operator. You will need to remove it from the window in order to ensure that all the dimensions match, especially the length of the two arms!

As for the handle and cover, see our 39-114L and 39-107, respectively.
