If you do not need to replace the front door control assembly I would not suggest to continue any further- That little spring took me a good 40 minutes to properly get back in place. It is Crucial to get it in right so that the Cassette door stays flush and closed.

Find Door Spring and remove carefully. Then find and pry off (on either side) glued on bumpers- These limit the distance the door hinge can travel in order to be pulled off---
