You should be able to remove the exterior vent panel from the outside and easily see the wooden pieces holding the refrigerator in place. When mine when out, I decided to replace it with an apartment sized refrigerator that almost exactly fit in the same cutout inside. I ended up having to enlarge the opening by about 1/2" on the sides and top but in now have a refrigerator that will work in the hot Arizona summers and cools down much faster.
