The fridge is usually held in place by 4 screws around the door frame. Undo these, and take off the outside covers to get to the back of the fridge. Everything should be attached to the back so nothing to remove there, but best to check. There is also a cover behind the control knobs at the front of the fridge. Pull off the knobs and remove the cover, then the fridge should just slide out of the frame.
