Hi. I also have a double-hung double-pane vinyl window with the interior
pane broken. Andersen Craftsman, I believe. Assuming that eventually I'm
going to have to bite the bullet and replace the whole dang sash ($90 + 3
weeks), I don't see any harm in first trying to replace just the broken
pane by myself. I mean, I can't break the window any more than it is
already right?

I was just wondering if anyone had any insight on doing this. I've gotten
the vinyl exterior trim off with some difficulty, so now the Insulated
Glass Unit is exposed. This consists of the two panes and the sealed
space between them. Now I'm struggling with how to pull it out of the
sash. It's either epoxied into the sash, or just wedged really tight.
Also considering trying to pull just the exterior pane off the IGU. But,
it's caulked on to the IGU frame pretty well.

My vision is that I'd be able to pull the IGU out with the square portion
intact (and perhaps the exterior pane unbroken), replace the interior
pane, then reassemble. Any advice?
