Were the doors removed?
For your convenience, the refrigerator doors have bottom hinges with door closers. These closers allow the doors to swing fully closed with just a gentle push. So that the closers feature will operate properly, the doors must be removed only when open to a 90° angle to the front of the cabinet. If one or both doors were not at a 90° angle when removed, the bottom door hinge must be reset.
