In this article, we will show you the 5 most common issues. But let’s start with some recent complaints from our visitor and then we will explain what you can do to fix these issues.

Here is what Darren says: I own a Samsung refrigerator that seems to have a problem with cooling in the fridge compartment, despite being several months old. The temperature is fluctuating and sometimes Samsung fridge not cooling at all.

I have tried doing everything I know to get it running normally again but no luck. Does anyone have an idea about what can possibly be wrong and how that can be fixed? Or is there a way it can be reset back to its initial state?

What causes Samsung fridge not cooling, but freezer works. 

The evaporator coils are frosted over:

When the evaporator coils get covered with frost, evaporator fan unable to circulate cold air within the fridge due to blockage and fridge will not be cooling. Initial problem related with defrost cycle.

Usually, the problem can be solved by changing the defrost temperature sensor. There are actually 2 identical temperature sensors. But you will need one with the white connector on the right side of the fridge.

If you see ice build-up on the back wall where is said “Twin Cooling” of your fridge or maybe you hear noise coming from the fridge, but when you open the door noise just gone?

That’s mean you have an issue with condensation which accumulates behind that panel and eventually becoming ice.

In this case, you need this Drain Repair Kit above and here is the video below what you need to do.

Evaporator fan frosted over:

Some people may complain about “Why Samsung fridge fan not working?” The main purpose of the fan is to circulate the cold air in the fridge. But when your Samsung fridge not cooling, one of the reasons for that is that your evaporator fan blocked by ice.

You need to check your evaporator fan to make sure it’s working or not.

If you have a french-door refrigerator, close the left door and put an ordinary magnet on the right side of the fridge to simulate the right door closing. After a couple of seconds, the evaporator fan should start spinning.

If you don’t hear the fan running, most likely fan blades blocked by ice.

Defective defrost heater :

Under normal circumstances the defrost heater assembly is responsible for defrosting any frost that been formed on the evaporator coils in the refrigerator, whose function is to allow cold air to freely flow thereby leading to the freezer cooling. However, when the defrost heater assembly is not functioning accordingly, excess frost will build upon the evaporator coils, as a result, the airflow will be restricted, which will result in the fridge not cooling. 

Defective thermistor or temperature sensor:

When working properly this component keeps in check the temperature of the refrigerator and transmits the information on the temperature reading to the control board so that appropriate power can be supplied to the evaporator fan as well as the compressor for effective cooling in return. But when the thermistor is defective both the compressor and the evaporator fan may not work properly.

Defrost thermostat failure:

This component allows the power to flow to the heater. When its failed, power will not flow and heater will not able to heats up and melt ice or frost which may build up on the evaporator coils.

What can be done to help the freezer start cooling again? 

Apart from replacing any components found defective, the following actions can be taken to fix the inability of the fridge to cool. 

In most cases, the inability of the Samsung fridge to cool is as a result of having excess ice frosting over the evaporating coils as well as the fan.

Therefore, one can easily initiate a FORCED DEFROST mode by pressing FREEZER and LIGHTING or ENERGY SAVER and FRIDGE buttons at the same time for 8 seconds.

Once you will hear one chime sound, press the LIGHTING button several times after that, until you will see Fd on the display.

This action activates the defrost element and melt the ice. 

To exit the Forced Defrost mode you can simply unplug power from the wall or wait 20 minutes till forced defrosting will be done.

In a nutshell, Samsung fridge inability to cool is one of the most inconveniencing challenges faced with the brand. Among the notable causes include the malfunctioning of various components that work together as a team to bring about cooling in a freezer, such as a compressor, defrost control board and the evaporator coils among others. 

Nevertheless, the Samsung fridge not cooling is not a permanent problem. Rather, this is something one can easily fix by simply making diagnostic tests on the components suspected to be defective, such as the ones mentioned above and have them replaced or even repaired where possible. Therefore, don’t let the Samsung fridge not cooling give you a headache when there is something you can do about it to bring back that peaceful mind and the beauty of the fridge.
