A refrigerator that is freezing foods can ruin fresh produce and the texture of your other foods stored inside your fridge. Here are some things to do and parts to check in order to fix this chilly problem.
First, check the temperature settings on your refrigerator. The optimal temperature settings should be around 38° to 36° Fahrenheit. If your refrigerator does not display a temperature setting, use a freestanding appliance thermometer to get an accurate reading inside your fridge.
If your refrigerator has numbers for its temperature control settings, try adjusting the settings. Usually, the lower the number on the control, the colder the temperature is set inside the fridge. Try going up one number in the settings to see if that prevents your food from freezing inside your fridge. Allow 24 hours for the changes to take affect inside the refrigerator.
Warning! Before attempting to work on any appliance, make sure that all power (electricity) and utilities (water and gas) have been turned off and/or disconnected on the appliance. Learn more about Appliance Repair Safety.Air Damper or Damper Control Assembly
The damper looks like a vent and is located on the side of the refrigerator. It allows cold air from the freezer to enter and cool items inside the refrigerator. Check the damper to make sure it is not stuck open.
The damper control assembly opens and closes the damper to allow the proper amount of cold air into the refrigeration compartment. If it malfunctions, then too much cold air will enter the refrigerator leading to food freezing.
Temperature Sensor or Thermistor
The temperature sensor or thermistor is located next to the air damper and detects the temperature inside the fridge. It sends this information to the electronic controls which can then adjust the air damper depending on these readings. If the sensor or thermistor is faulty, then the electronic controls may not adjust the damper properly.
Cold Control Thermostat
The cold control thermostat maintains the temperature of the refrigerator. It powers the compressors and evaporator fan on and off in order to maintain the selected temperature setting. A faulty cold control thermostat could lead to food in the refrigerator freezing.
Main Control Board
Some refrigerators have electronic control boards that maintain all the functions of a refrigerator. Before replacing this part, make sure that you eliminate the other parts listed above, before considering replacing this part.
Keep in mind, some parts of your refrigerator will be colder than others, like spots in the back and at the bottom of the refrigerator. If only certain foods are freezing and they are located in these spots, consider moving them to other areas inside your refrigerator.
