Refrigerator Freezing Food

The parts or condition listed below for the symptom Refrigerator Freezing Food are ordered from most likely to least likely to occur

Commercial Refrigerator Freezing Food

Cause 1 – Temperature Control Thermostat

The temperature control thermostat send voltage to the compressor, evaporator fan motor, and the condenser fan motor, provided there is one. If the temperature control thermostat is not working well, then it can cause the cooling system to run longer than necessary. So, the refrigerator will be too cold. To see whether the thermostat is working well, change the thermostat from the lowest setting to the highest setting and listen for a click. If it clicks, then it is probably working fine. Use a multimeter to test the thermostat for continuity if you do not hear a click. If the temperature control thermostat does not have continuity, then you must replace it.This the first probability if Refrigerator Freezing Food

Cause 2 – Thermistor

The thermistor checks the temperature of the air and sends that information to the control board. The control board then sends power to the compressor and evaporator fan depending on the reading from the thermistor. If the thermistor is not working well, the compressor and evaporator fan can run too often. So, the refrigerator will be colder than it should be. Test the thermistor with a multimeter to see whether it is working well. The thermistor resistance should change along with the temperature of the refrigerator. If it does not change, or the thermistor does not have continuity, then you must replace it.This the second probability if Refrigerator Freezing Food

Cause 3 – Temperature Control Board

The temperature control board gives voltage to the compressor and fan motors. If the control board is not working well, it can send nonstop voltage to the compressor or fan motors. So, the refrigerator will be too cold. Test all of the more commonly defective components before replacing the control board, as it is often misdiagnosed. You should consider replacing the temperature control board provided that all the other components are working well.

Cause 4 – Main Control Board

The main control board can stop working properly. This is, however, uncommon. Test the more commonly defective components before replacing the control board. Consider replacing the main control board if all the other components are working well.

Cause 5 – Damper Control Assembly

The air damper control opens and closes, allowing cold air into the refrigerator. If it is not closing as it should be, then it can let in too much cold air. Inspect the damper control to see whether or not it is working well.

Cause 6 – Damper

The damper opens and closes, allowing cold air into the refrigerator. If it is stuck open, then it will let in too much cold air. So, the refrigerator will be colder than it should. Inspect the damper to see where or not it is working well. This the lower probability if Refrigerator Freezing Food

One thought on “Refrigerator Freezing Food

  1. Thank you very much for this article, it has been very interesting for me. For a while now, my refrigerator has been freezing my food and i hadn´t found the cause for the problem. I have called many repairing agencies and none of them have had a solution to my problem. I was very worried because this refrigerator has been in my family for ten years and i wouldn´t like to get rid of it. Know that I have read your article, I am relieved because I discovered what was happening; my refrigerator, as I have said before, is a little bit old, so its temperature control board was malfunctioning, the problem was that the temperature control board was sending to much voltage to the fan motors. If I had read your great article before I wouldn’t have spent so much money in bad technicians and in food, because everything I had bought froze. I know that eventually I would have to change this old refrigerator, but in the mean while I would like to conserve it, because it has been the best refrigerator my family has had.
