Thanks! I appreciate your help.
For what it is worth, this is what I ended up doing:
Removed #6
Pulled #4 away from the rest by removing a screw on top and bottom (maybe #7)
This released #2, which then allowed the door to be lifted off.
15 minutes, max - once I decided to just go for it.
I haven't put the new one on yet though. I am too afraid of cracking it while taking it apart.
