But before we proceed, let’s look at some of the comments we get regarding cooling issues. After that, we will move on to the causes and fixes.

Simon says: “I have a Samsung fridge. Recently it’s not getting very cold or not cold at all for both refrigerator and freezer. I have googled some troubleshooting myself, but not much luck. The only thing I have tried so far is turned it off for 24 hours, then turn it back on, and it seems to run normally for maybe a few days before the same issue starts again. Can you please guide me on this?”

Malena says: “We have a 2-year-old household Samsung refrigerator with bottom drawer/door freezer. The problem is the upper fridge half will not get over 50 degrees F.
Any ideas?”

What Causes Samsung Fridge Not Cooling? Troubleshooting and Diagnosis

What Causes Samsung Fridge Not Cooling? Troubleshooting and Diagnosis

Let’s look at the possible causes and solutions for it.

Condenser Coils are Dirty

The condenser coil‘s main function is to dissipate heat as the cold refrigerant passes through it, thereby cooling the fridge. You can locate it under the bottom of the refrigerator.

But before we proceed, let’s look at some of the comments we get regarding cooling issues. After that, we will move on to the causes and fixes.

As time passes, the condenser coil may become dirty, and hence it won’t function correctly. It results in improper or no cooling inside the fridge.

Inspect the condenser coil and check if there is dirt on it. Switch Off the fridge and clean the dirty condenser. In most cases, it will fix the problem.

The Evaporator Coils are Frosted Over

If you are using your refrigerator for a long time, then there is a high chance that the evaporator coil is frosted. The chance of evaporator coil frosting increases even more when you frequently open the fridge to take out/in food items.

When the evaporator coil gets frosted, it hinders the circulation of cold air in the fridge. So the fan will be unable to draw air over the evaporator coil. The air will be less cool, and hence Samsung Fridge Not Cooling problem will occur.

Many times, by simply changing the defrost temperature sensor, you can fix the issue. But it may not work in all cases. The defrost temperature sensor is the one that has a white connector on the right side of the fridge.

Evaporator Fan Frosted Over

The fan is responsible for circulating cold air from the evaporator coil to the rest of the refrigerator.

If due to some reason, the fan becomes faulty, then it won’t be able to function correctly. It results in the Samsung Fridge Not Cooling, But Freezer Works problem. As a result, your food will deteriorate after some time.

In a french-door refrigerator, you can close the left door and then put a magnet on the refrigerator’s right side. It will stimulate the closing of the right door. In most cases, the evaporator fan will start spinning after a few seconds.

If the problem persists, then the issue may be due to the ice blocking the fan blades. So, you can try by switching off the fridge and wait for a few hours before starting it again. We hope that this will solve the Samsung Fridge Not Cooling issue.

Defrost Heater is Defective

The defrost heater’s primary function is to defrost any frost that may form on the evaporator coils.

So if the defrost heater becomes faulty, then the evaporator coils will get frosted, and hence the cool air will not be able to flow freely inside the refrigerator. It will result in the refrigerator not cooling problem.

Test the defrost heater using a multimeter. If it fails the continuity test, then replace the defective defrost heater.

Faulty Thermistor Or Temperature Sensor

The thermistor in the fridge helps monitor the temperature and sends the signals to the main control board. If the temperature increases too much or too low, the control board adjusts the fan and compressor’s power. Hence fridge temperature is always in control.

Sometimes the thermistor may become defective and hence will not send temperature to the main control board. So the evaporator fan and compressor may not run properly. The Fridge will not get cooling.

You can test the thermistor using a multimeter to determine if it’s defective or not. The thermistor resistance should change with temperature. If you get a constant reading of resistance, then you should replace the thermistor.

Defrost Thermostat is not working

Defrost Thermostat helps in controlling the power to the heater.

If the thermostat fails, then the heater will not get the power, and it will not heat up. So the evaporator coils can get frosted over.

Use a multimeter and test the thermostat. You should replace the defective part.

Main Control Board is faulty

If the main control board is faulty, then the fridge will not work. However, in most cases, the main control board is not faulty. So, you should check other critical components of the refrigerator before replacing the main control board.

What to do when Fridge Not Cooling

You may have to replace the defective parts to make the fridge work again. In most cases, the repair is costly, so it will be easy to buy a new part and replace the old part.

As we have already said earlier, the most common cause of refrigerator not cooling is frost over the evaporating coils and fan.

Many Samsung refrigerator comes with a DEFROST mode. You can put your fridge on FORCED DEFROST mode that will help in removing the frost.

Samsung Fridge is not cooling is one of the top issues on Samsung refrigerator. But, it is effortless to fix by doing simple tests on specific parts of the fridge. For more complicated issues, please do contact the Samsung repair center.
