Need Help With Refrigerator Not Cooling

My Refrigerator Side Does Not Get Cold But The Freezer Side Does Is There A Reset Button For The Compressor Or Some Type Of Start Up Relay I Need To Reset

Cold air enters the fridge through a damper or vent between the freezer and fridge. The evaporator fan in or behind the freezer blows the air through. There is an adjustment to open and close this vent to allow more or less cold air in. Here is a diagram of the controls of your fridge. http://www.appliancepartspros.com/sect/b/e/r/ber79xcxi6.gif
