The 39-286 might work for you, but this is a very old Andersen design that isn't made anymore, so I can't be certain. Remove the old crank handle and measure the hole that accepts the spline. If it has a 3/8" diameter, then the 39-286 might work. Note that if the entire operator has broken down though, you'll need to replace the whole mechanism. See if our 39-094 matches up. Another option would be to use our 39-365, but it will be a little tricky, since it uses a different track, the 39-504, that needs to be mounted to the bottom of the sash. I can't be sure, but maybe you can use your existing track with the 39-365 operator as long as the end bearing fits. I believe either operator will take some adapting to fit no matter what. |
