Never mind! I decided to go ahead and give it a try, and it worked out just fine. In case someone is searching for a similar solution, here is what I did. Instead of taking the huge and very heavy door down for the repair, I simply undid the two screws that held the right side of the frame to the rest of the frame. The right side popped right off. All I needed to do was put the rubber "gasket" back on the mirror edge (easy) and then carefully reattach the right side, pushing the mirror\gasket into the frame's channel. Piece of cake. The only thing that caused any work was the fact that the right roller on my door is attached to the right side of the frame. Pulling the side away meant that the mirror and the rest of the frame was no longer supported by the roller. To be able to reattach the right side, I had to have a friend lift the mirror door a bit before inserting the mirror into the right side.

Hope this helps someone!

Thx for that advise , so helpful

Surely she did.

This has hopefully answered my question that I’ve been searching days for!....will try this tomorrow and save myself $250 (which has been quoted for the fix)!...
Thank you
