All of the places that sell replacement remotes references to Linear.

I don't know if they bought out Moore-o-matic or if this just made the electronics for them.

But I don't have any idea of how to match them up to your model.

Start with the Delta 3 look if any of the remotes look like yours then click on that and there will be a link for programing instructions.

If none match then try the Delta 3.

If noe match then try the opener manuals.

Or you contact aaaremotes to see if they can direct you.

or Linear tech support.

Thanks I will give it a shot.
