Replace window crank and case
Hey there!
Thank you for reaching out to us. We're happy to help with this. The worm gear coming out with the handle indicates that the operator must be replaced. Can you show us a photo of the window open so that the operator's arms that move the sash are fully visible? That will allow us to narrow down some options.
Great! We'll be here to help whenever you can get that for us, no rush.
Hmm, our part identifier appears to be having a hiccup. Could you please email your photos to help@swisco.com with the D349889 reference number?
Great, thank you! Take a look at the 39-031 & 39-032 and 39-155 & 39-156 operators. The important difference between them is the length of the link arm. If you wanted a new cover and handle, see the 39-107 and 39-114L which are sold separately.
Review the specifications for these parts and see how they compare with yours.
