Hello and welcome to just answer my name is ***** ***** I will be the one to assist you .Since the freezer is still keeping temp and freezing that leaves out the big parts such as pricey compressors and more that likely your control board. Since it is just the fridge more than likely this is an issue with either the condenser coils being frozen or the evap fan not working or the more than likely culprit of the damper assembly or thermistor causing the issue.
None of which are hard or to expensive to fix or replace if you are interested in doing the troubleshooting and work yourself with my assistance of course.
