Andersen window crank replacement

Thanks for posting. Start by looking at our 39-264 Operator. This seems to have a similar design to your old mechanism, but review the dimensions below to confirm it matches what you have.

Dimensions for 39-264

For a handle and cover that works with this operator, see the 39-286 and 39-152, respectively. Also, if your window was built between 1995 and 1998, you will need the 39-362 Adapter Plate. Finally, if you need to replace the hinges in the window as well, you should be able to use our 36-048, so long as you replace both the lower and upper hinge in the window at the same time so the operation remains symmetrical. The video below shows how to do this. Let me know if you have further questions.
