Searching for 9970A-3A

A quick learner says:
The second photo show the number 9970A-3A. The window opens but when closing it hits a point where it jams up and won't close any further.

Thanks for looking at this.

Oh boy, I knew I'd run into this again some day. This is an old type of Andersen casement window operator that is no longer made. We've talked to Andersen about it a few times and there is no direct replacement. Now, typically, we recommend looking at our 39-264 operator, which is the closest existing match, in addition to the 39-362 adapter plate, which is used to help the 39-264 install on some specific Andersen windows made after 1999.

Unfortunately, we've never had any confirmation as to whether or not these worked. I just checked our backlog and no customer who used these ever got back to us. I'm afraid I cannot guarantee that this is a solution, and if it is, I cannot be sure if it won't take some measure of handy work to get it to install.

Look over these parts carefully either way and let me know what you think.
A home owner from California says:
Thanks Tom. I ordered both parts and I will let you know if they work. It should. The only thing I see is that the stud bracket faces down so I will have to remove the stud bracket lock from the new casement window operator and flip it over. I assume I can do this as it comes right off of the old crank arm. Thanks for your help.

I have 2 9970A-3A operators. Both stripped internally. Shaft spins but arm does not move. It has been 6 years since this original post. Has it been determined if the 39-264 with or without the adapter plate will work to replace this?

Thank you,

Tom

Hello, Tom. We unfortunately have not received verification that our proposed solution works. However it remains our best option at this time.

I am sorry for the inconvenience. 

A home owner from Colorado says:
I have these same Anderson crank operators that are failing and want to give the 39-264 and 39-362 a try. I took one of the existing Anderson cranks off and it has the piece on the end of the arm to attach it to the vertical part of the window. Is something like this available, o do I need to attach the arm to underneath the window now?

We unfortunately don't have a sash bracket that matches what you show here. I can at least tell you that the 39-264 is designed to connect to the sash using brackets like our 39-531 and 39-530 . these screw to the underside of the sash, specifically. You will need to check if you have room to install these (or if drilling new holes down there is even possible).
