Casement window opener

Sounds like the operator gears are stripped out, so it'll have to be replaced.

We can help, but we need to see the entire operator, not just the base. That unfortunately means you'll need to remove it from the window in its entirety so that we can examine the entire assembly.

Once we do that, we can check our inventory for a match. Given that this is an Andersen brand window, I'm confident that we have something that will work. We just need to narrow down the list of possibilities.
