Bathroom crank window
Looks like your worm gear came out of the operator. This cannot be repaired or replaced, unfortunately, so you need a new operator entirely.
In order to make a recommendation, I will require more information from you. To start, I need a clear photo that shows me the complete screw hole pattern of the operator, top and bottom, in one shot.
I will also need you to disconnect the operator from the window hinge and show me a clear picture of the link arm.
Once I have these two pieces of information, I will see if we have a match in our inventory.
Hey there, maybe I can help. Take a look at he 39-259 operator, which is used on VE Andersen windows, along with the related video. This looks like the operator you are looking for but review its specs to confirm.
