Can anyone tell me how to tighten the door handle. The refrigerator handle (upper part) has come loose. I am not sure how to even access the bolt/screw to tighten it.

Take a look in section 06.
Handle has to go up to release it from the clup.
If you click on the picture of Item 5 clip and on Item 8 Handle, Center (white) a new page will open with more info which should be useful to you.
