The crank opens the window, but will not close the window. The worm gear just unscrews itself.

Hello,

The broken worm gear indicates that you will need to replace the whole assembly. If you could open the window and show us the arms that move the sash in and out, that will help us confirm the correct replacement. Thank you!

Photos are as close as I could manage without taking the sill apart.

Take a look and compare our 39-216 operator to your original assembly, along with the related items on our product page. Thank you!
