frigidaire refrigerator door making clicking noise when open.

I have a side by side Frigidaire refrigerator. The door make a clicking sound when the door on the refrigerator side is open. The freezer side is ok. Can you tell me what is the problem with the door? Do I need to adjust the door or replace parts for the door?

Here are your parts

Could be that a door cam is broken.
Take a look at the hinge cam (Item 22 in Section 1) and the door cam (Item 22 in Section 7).

Click on their picture to get better/more views of the part.

If one is broken I would replace both of them.
