Silhouette by Dometic RV fridge

Question

I own a 1994 24 Foot Scotty, newly acquired (not new). In testing out the fridge at home, I noticed that the freezer works but not the refrigerator (sorry spelling) part. I read in the manual that the most common problem for the fridge not to work properly would be because of a blow fuse. Now I haven't gotten new ones yet, but could anyone explain why the freezer would work but not the other part?
