Freezer display temp does not match actual temp

Freezer display temp does not match actual temp I have a GE profit refrigerator/freezer. The user interface displays the actual temp of the freezer as -9*, but the actual temp is 20*. I have replaced both thermistors and the control board. It is still doing it. I can put the user interface into test mode and everything tests normally. I set it to prechill mode and it will get to the correct temp in the freezer, and read the correct temp for a while. But ultimately the user display will go back to registering -9* as the actual temp but it will only be 20*.

"Hi @Candy Aaron

What is the model number of the refrigerator?

Can you hear if the evaporator fan inside the freezer compartment is operating?

It will stop when the door is open and start again when it is shut (either door -freezer or refrigerator), so you may be able to hear it that way.

If you can't hear it then there is either a defrost problem or an evaporator fan problem. The fan should operate as long as the compressor motor is running.

A defrost problem means that ice builds up on the evaporator unit and eventually ices up the fan which stops it from working. It is the evaporator fan that blows the cold air from the freezer compartment into the refrigerator compartment to cool it down to the set temperature.

The causes of a defrost problem could be either a faulty defrost heater, faulty defrost thermostat (or thermistor), blocked drain from the freezer to the evap pan under the compartment or a faulty control board

A fan problem could be a faulty fan or loose fan blade or a faulty control board.

If you can hear it, then it may be an air damper problem

Note: All the above is for a refrigerator model that has only the one evaporator unit and not two i.e. one in the freezer only and not one in the freezer and one in the refrigerator. That’s why knowing the model number helps as it can be other problems for a model with two evaporator units."
