Part #30866 is the same but the old one doesn't have part #40394 that is the middle piece. It's longer than the old one. I have the pictures of the model and size that I take from the window frame. How can match size? Please help me! Thank you

Thanks for posting. Sorry to see the 39-089 didn't work for you. View our Return Policy here. I believe I see the problem. The 39-089 has a Z-shaped gear arm, whereas your old operator has an extra bend near the bending point, forming a W. See our 39-187 instead. I believe this is the better match. Take a look and see if you agree.
