Broken inner door glass
I removed all the screws attaching the inner liner to the door, then removed the broken glass. I did this before ordering the replacement glass so I could be sure that only one piece was broken -- the door contains four pieces of glass in all. After the replacement glass arrived (really fast delivery!), I cleaned all the parts and reassembled the door. I had some difficulty in aligning the screw holes properly, and I'm still not sure if I have the exterior sheet of glass positioned correctly -- the schematic shows the order in which the parts go together but not how they fit exactly. I should have inspected the door more closely before I took it apart. Anyway, it feels solid and everything seems to work.

Inner glass
Take door off completely by setting hinge locks into place and then removing door. Take all of the screws out from frame (remember that the flat screws go the outside and the raised heads on the inside of door)Remove the clips on the bottom of door as well. Carefully remove frame. Then remove the inner glass clips, this will allow you to remove the broke or cracked glass easily and install the new glass. Set the door on a soft towel with finish side down. Make sure your hinges are on the proper sides if you moved them. (you will see where the screw hole matches up with the bottom of the frame. Do everything in reverse to put back together. Good Luck
