Cause 1
The Evaporator Coils are Frosted Over
The defrost heater assembly turns on a few times throughout the day to melt away any frost that may have accumulated on the evaporator coils. If the defrost heater assembly is defective, frost will continue to accumulate on the evaporator coils, and the coils will become plugged with frost. If the evaporator coils are frosted over, the airflow through the coils will be restricted, causing the refrigerator not to cool. Check the evaporator coils to determine if they are frosted over. If the evaporator coils are frosted over, test each component of the defrost system.
Cause 2
Evaporator Fan Motor
The evaporator fan motor draws cold air over the evaporator coils and circulates it throughout the freezer. If the evaporator fan is not working, the freezer or refrigerator will not cool adequately. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor..
Cause 3
Damper Control Assembly
The air damper control opens and closes to let the proper amount of cold air into the refrigerator compartment. If the damper does not open properly, it won’t let enough cold air into the refrigerator. Check the damper control to determine if it is broken or stuck closed.

@tmosely1 my answer addresses this.

This is an old post but for those looking it up today........ The thermostat on the coils is more than likely bad. Inside the freezer where the coils are(you have to unscrew some panels) it is usually round ,about the size of a quarter maybe a half inch tall, with 2 wires . This clips and un-clips very easy. You might have to use a hairdryer to melt the ice to get to it. Clip the wires (close to the old one) so you give yourself enough room to attach the new. About a $10.00 part

What is the make and model number of the refrigerator?
Can you hear if the evaporator fan in the freezer compartment is working?
It will stop if a door is opened (either door) so you will have to try and hear it stop and start again when you open and close a door.
