Why Samsung Fridge Not Cooling? Expert Explain

Samsung refrigerators have their difficulties even if they are brand new. But unlike other devices, when the refrigerator does not cool enough or does not cool at all, you might have a big problem. In this article we’ll talk about that and what to do in this situation. So, let’s start!

Why Samsung Fridge Is Not Cooling?

So Why Samsung Fridge Not Cooling? Usually, the main problem why Samsung fridge is not cooling is a broken evaporator fan motor. The purpose of that motor is to draw cold air into the evaporator coils which then circulate throughout the fridge. If the fan motor fails, there won’t be cold air, and the refrigerator will not be cooling.

If the fan evaporator motor is running and your Samsung fridge is still not cooling, make sure to check the power outlet for the fridge.  Also, make sure that the temperature of the fridge is well adjusted to the temperature in the room in which it is located. 

It is known that when the room is additionally heated, the fridge needs more power. In some cases, the problem can be solved by moving your fridge to another location in your house. There are a number of other reasons that can prevent a fridge from cooling at full capacity. Below we bring you an overview of the potential reasons why the Samsung refrigerator does not cool.

Samsung Fridge Not Cooling

Faulty Evaporator Fan Motor

As already mentioned, one of the common reasons why the Samsung refrigerator does not work is a broken evaporator fan motor. Its main task is to draw cold air into the evaporator coils that then circulate throughout the device. When the evaporator fan motor fails, there is a lack of cold air and the refrigerator cannot cool.

How to Fix

The first step is to find where the evaporator fan motor is located in the refrigerator and try to start it manually. If you fail to start the motor manually, or you can do it but it only rotates with more applied force, you have to buy a new evaporator fan motor. If you can turn the motor by hand but do not continue to run, it is time to call an expert to help eliminate the problem

Air Damper Control

Another possible reason why your Samsung fridge does not work is because of the air damper control. It is a part of the refrigerator that opens and closes and lets the cold air reach all compartments. Its main function is to supply the fridge with a certain amount of cold air that is sufficient to bring the temperature down. The air damper control should be checked. If it is stuck in the closed position or if it does not work at all when the refrigerator is turned on there is a chance that you’ll need to buy a new part.

Temperature Control Board

The Samsung fridge may not cool because of the malfunction of the temperature control board that is located inside the fridge. To test this problem, you need to have some knowledge. It is a part of a device whose task is to supply voltage to the fan motors and compressors. If you have a broken control board, your fridge won’t receive signals and will not function properly.

Call Professional

Since the control board that controls the temperature of the refrigerator is a part that is very expensive, it would be best to leave the repair to a professional. This is one of the most common failures that can happen. Therefore, if you believe that your refrigerator is not cooling well due to a problem with the temperature control board, it is best to call a repairman.

Defrost Thermostat Failure

With the help of this component, electricity reaches the heater. When this component is broken, the power supply to the heater is interrupted and it can no longer heat up and melt ice that can build up on the evaporator coils. 

In addition to the fact that the refrigerator that does not cool down can be repaired by replacing broken parts, it is possible to take some other actions to start the refrigerator to cool down again. In many cases, the Samsung refrigerator does not cool down enough because too many deposits of ice have formed on the evaporator coils and/or fan.

If this is the case, anyone can easily run the FORCED DEFROST function. This can be done by pressing simultaneously the LIGHTING and FREEZER buttons or FRIDGE and ENERGY SAVER for 8 seconds. 

After the ringtone sounds, press the LIGHTING button again several times in a row until ‘Fd’ appears on the display.

Solution To Samsung Fridge Cooling Problems

The DIY secondary heater can help you remove ice deposits that have gotten on the outside of the evaporator coil. They are an obstacle to the circulation of air in the refrigerator and adequate cooling of the device.

What If Samsung Fridge Not Cooling but Freezer Is Working?

Frosted Evaporator Coils

There are several reasons why the Samsung fridge may not cool even though the freezer is working. The most common reason is that the evaporator coils are frosted. When this happens, two possible problems need to be discussed: evaporator coils and defrost heater assembly. 

Keep in mind that defrost heater during the day will turn on a few times. Its function is to melt the ice that has formed on the evaporator coils. Without this cooler function, ice will accumulate on the evaporator coils until it fully blocks the air to flow through the device. Without airflow that goes true the refrigerator, the appliance will not cool down even when the freezer is operating normally.

How to Fix / Need Repairman

To check if the frozen evaporator coils are the reason why your refrigerator does not cool enough, you need to see if it’s covered with ice. If there are deposits of ice on the evaporator coils, you need to check one part of the defrost system and determine if it works. Note, replacing any part that turns out to be faulty is a challenging task. It is therefore advisable to call a professional for repair after finding out which part is the problem.

Faulty Thermistor

It often happens that the Samsung fridge does not cool enough if the thermistor is faulty. This is the part whose function is to monitor the temperature of the refrigerator and send that data to the control board of the device. After receiving data from the thermistor the control board coordinates the operation of the compressor power and fan evaporator to achieve the ideal temperature in the refrigerator

These two are usually the main reasons why a Samsung fridge works but doesn’t cool enough. But there are a number of other reasons that cause this to happen. It would be best to hire an expert to inspect your refrigerator.

What If Samsung Fridge and Freezer Are Not Cooling?

The first step in solving this problem is to check that your Samsung refrigerator is properly connected to a power source. If you find that everything is OK with the power source, unplug the fridge from the wall outlet and try plugging in another appliance instead. If it turns out that the other device does not work either, you need to reset the circuit breaker that is connected to the outlet that you’ve used.

After resetting the fuse, if the fridge starts to work, reduce the refrigerator’s temperature and let it run for a few hours. Additional help in solving the problem can be moving the fridge to another location in the house where the fridge will not be exposed to direct heat sources such as sunlight. If the refrigerator is exposed to a heat source, it is forced to work harder than usual, and it may seem that the device does not cool for several hours.

You can reset the Samsung fridge by simply unplugging it from the grid and turning it on again after one minute. If the problem is caused by the device configuration, be sure to reset it. This is especially applied if you have just started using a new refrigerator. 

All the solutions that are offered here for situations where the refrigerator and freezer do not cool as they should do not represent a universal fix. If you have tried all the options offered in this text, and your Samsung cooler still has a problem with cooling, it is time to contact a professional who will know best how to troubleshoot the device.

What If Fridge Not Staying Cold or Cold Enough?

Ambient Temperature

The temperature of the room where the refrigerator is located may be the reason why your Samsung fridge is not cooling enough. A simple solution is to move the refrigerator to another location in the house that is not so exposed to heat sources. It should be borne in mind that the refrigerator works much harder to maintain the temperature inside the device when it is in a room where the air temperature is high.

Refrigerator Parts

In addition to placing the refrigerator in the right place in the household, there are three important things that prevent excessive cooling of the device: defrost timer, defrost thermostat and defrost control board. If any of these three devices are faulty the fridge may remain permanently stuck in defrost mode. When the fridge is in defrost mode it maintains a cool temperature in the appliance but still cannot cool it efficiently.

How to Fix This Problem?

It is important to know that if any of the above parts of the refrigerator are broken, you don’t replace them on your own. This is a job for a professional since without enough knowledge about repairing a refrigerator it is easily possible to do more damage to your fridge. An expert will perform the right tests to determine exactly which part needs to be repaired.
