My Sub Zero refrigerator fan and compressor run constantly. The freezer is fine, the fridge side won't cool below about 55 on hot days (we don't have AC). In the winter It's fine. Temp setting at 10 in summer, 7 in winter. I vacuum the unit frequently, so it's not blocked inside with dust. Is it possible that it needs a charge? What about line blockage?

Sounds like low on freon. Suggest having it checked by a professional with gauges....
