Window crank

A home owner from New Hyde Park, NY says:
The crank started wiggling then came out. I tried to screw it back in, but it could not catch on the inside. Do I need to replace everything or just the handle? Also, I am not very handy. Will replacing it be a task?

Looks like the worm gear has stripped out. This cannot be repaired or replaced, unfortunately. You need an all new operator.

We can help, but we will need to see more of the operator itself. Specifically, I would like you to open the window as far as it can go and show me a clear, top-down view of the mechanism. That will allow me to match it up to something in our catalog.

Hi Tom, hope this helps.

That's a huge help, thank you! With these photos in mind, I recommend the 39-031 and 39-032 operators. I am confident that these will replace your originals.

Hi Tom, how difficult is it that install the new operator and crank ? Does the window need to be removed?

It's not difficult, in my experience. The hardest part in your case may be due to the fact that you have a vinyl window. You need to find a way to get the vinyl sill trim up and off the operator so that you can access the screws, but that's tough because it differs from window to window. Sometimes it can be pried up, sometimes you have to take the frame apart.

If you aren't handy, or if you don't want to experiment, you may want to have a local professional come out and do it for you. Otherwise, as long as you can access the screws, installation is as simple as unscrewing the old one and screwing the new one on. The video below goes into more detail, though for a wood window.
