I have a 23' free standimg dispensing side by side ref. my ref is not cooling but the freeze part is working

Usually if the freezer is working and the refrigerator is not there are a couple things to look for you can have a look at this site it explains in detail what to look for:
Refrigerator Wont Get Cold But Freezer Will

When you open the freezer door do you hear the fan blowing?all that happens is the evaporator coil in the freezer gets cold,the evap fan blows the cold air from the freezer and into the fridge side,there are ducts on the bottom left side where the air return sto the freezer,if that's blocked the fridge will get warm,also if the fan is blowing depending on your model you could have a damper,it's in the fridge section up top where the cold air blows into,all it is is a door that opens and closes to let the air in when the fridge section gets warm and then it closes when it's cold enough,if the damper is bad it won't open and let the air in,sometimes it gets stuck in the open position and things start to freeze in the fridge section.if you can't figure it out send the model number and i can see what model you have,open the fridge door,look up on the right side near the ceiling and you should see a tag with the model number.good luck and have a great weekend.also from the bottom up in the freezer,remove the second bin of food and touch the back inside wall of the freezer,if there's frost or like snow on the back inside wall of the freezer you have a defrost problem,let me know what you find.
