I have the following door handle, that rotates 180 degrees. The position allows the door to be totally opened, closed, or just half opened as a window.
The problem is it keeps coming out, but this didnt happen before.
Is there a handle on the outside? Does the outside handle come off when the inside handle comes off? Look at the end of the square shaft coming out of the handle. Does it look like there might be a screw running through the shaft?
I think the square shaft should be affixed to the outside handle, and then the inside handle is removable via the set screw that @huesmann mentioned.
If that is correct, then the question becomes why is the square shaft not staying with the outside handle. Remove outside faceplate to have a better look. Maybe a missing clip. Maybe a factory press-fit that is no longer tight.
The OP should go to the website and work his way to Service and Downloads. He can identify what he has, I can't, and download Installation and Service documents. With the documents, he should be able to figure out what's going on with the handle.
