refrigerator food freezing

Hello. I have a side by side GE refrigerator that the fresh food is freezing. I was reading some of the other threads regarding the damper assemby but I am not sure how to get to the damper assembly in the fridge. I started to take off the cover but not exactly sure what to do next. Do I need to take off the light to get at the damper? And if I do, How do I check to make sure this is the problem. Thanks in advance for your help.
