Question about Refrigerators
the fact that you found ice on the coils at the back of the fridge means that there is a problem with the defrost system.
The defrost system ensures that coils are not icing up, and it is composed by a fan , the evaporation coil, and a defrost thermostat that start energy to the coil.
If the fan is working, then faulty parts are either the defrost thermostat or the coil.
the evaporation coil can be tested reading ohms with a multimeter, if there is infinite impedance between the two coils contacts, that means that coil must be replaced.
The thermostat is more difficult to test, and returns about 1kohms at ambient temp.
On your fridge there is also an additional 38 degrees defrost thermostat that must be tested.
Here the parts:

Hello friend, thanks for your post!
I see your Frigidaire refrigerator is not freezing in the freezer section but keeping your fresh food side cool. Some possibilities could be your refrigerator stuck in defrost mode, the control panel, or sealed system. I would recommend performing a reset on your appliance which would be flipping your household circuit breaker off for ten minutes. If that does not resolve your issue I would seek assistance from a professional to properly diagnose and repair your appliance. -Matt
