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.

Tips for a great answer:
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

Hello Cory Mitchell - If your freezer is not cooling, it could have a floating restriction in the lines or something more complicated like an issue with the seal system that only a professional can repair. This can conclude the compressor not working correctly, the evaporator fan not turning, or even coolant in the lines at incorrect levels to properly cool. If the compressor was running, humming or even a little warm then that was typically normal. Also try checking and see if the door seal is bad; place a dollar bill between the body of the freezer and the door. Now close the door. The dollar bill should stay in place and pull out with a small amount of resistance. If the dollar bill falls out when placed between the gasket and cabinet double check to see if the door is being blocked by anything stopping it from closing. If it proves to be ineffective, connect with a professional to accurately pinpoint any potentially more serious issues.
