The freezer side it's not cooling, the refrigerator side seems to be working fine, the setting show be correct.
You will want to pull the rear wall off the freezer and check for the evaporator coil to see if it is frozen over. If so then you will want to check the defrost sensor to make sure that it is good. If faulty it would need to be replaced. The resistance of the sensor should be 5K ohms at room temperature.
