I was given an Admiral Refrigerator to use in my garage. The model number is NT17L4. When I checked it out, it was working well. It was very cool. It was delivered today. When I plugged it in, the freezer gets real cold, but the refrigerator is barely cool. It only traveled about one block, and was delivered by an appliance company. What could be wrong? Any suggestions? Should I vaccuum the coils underneath? Thanks, Tim
