Dorm frig

Our compact frig is freezing everything.  I figured out the problem tonight and we cannot solve it before moving my son to college on Thursday.  Consumer Reports just did a new report on compact refrigerators and found they were all so horrible they could only recommend one.  And that one is just over the size limits for my son's dorm.  I'm so frustrated.  It cannot be this difficult to keep insulin safely.  Advice?
