Remove the gray plastic vent that covers the bottom of the refrigerator (it just pulls off). On mine, there are black plates that are screwed to the bottom of the refrigerator and to the cabinet. I believe that if you remove those that the refrigerator will just slide out. Not 100% sure but just from what I can see, that should allow you to remove it. I noticed on mine the other day that if you push on the top part of the refrigerator that it will rock back and forth. Seems very unstable to me.
