Side by Side Fridge running but not cooling?

Hi, I have a fridge made by GE Model Number: GSL22JFTA

The fridge is running constantly, but the inside of the freezer just gets warmer and warmer. I tried unplugging the fridge for a day and turned it back on the next and still nothing. There doesn't seem to be frost build up, but it could have melted when I left it off overnight. I have set the temperature to the lowest possible and still very warm. Water dispenser and everything else still works.

Help would be much appreciated. Thanks.
