Samsung makes very high-quality home appliances, including refrigerators. However, sometimes their appliances can break down and need to be repaired. One of the most common faults people have with their refrigerators is that they won’t cool properly.
If you check each of the components in this article, you should be able to find the cause and fix it.
This guide covers all major models of Samsung refrigerators, including:

The best place to start if your refrigerator won’t cool is to check the condenser coils to see if they are dirty. The condenser coils are important, as they help to keep the refrigerator cool by dissipating heat when the refrigerant passes through them.
Here’s how to check the condenser coils:
The next component to check is the condenser fan. The condenser fan helps to spread air through the condenser coils and onto the compressor. If the fan doesn’t work properly, the refrigerator won’t cool.
To check the condenser fan motor:
Another possible cause of your refrigerator not cooling is a faulty evaporator fan. This fan can be found in the freezer compartment.
To check the evaporator fan, you need to:
Another possible reason why your Samsung refrigerator isn’t cooling is a faulty start relay. The start relay helps your refrigerator to cool down by working with the start winding to start the compressor.
The best way to check if it is faulty is to:
If the start relay works correctly, check the temperature control thermostat. The thermostat sends voltage to the compressor, evaporator fan motor, and condenser fan motor based on the temperature of your refrigerator.
Here’s how to check the temperature control thermostat:
Next up is the start capacitor. This component provides a boost of power to the compressor when it is trying to start up, so if it fails, the compressor won’t work and the refrigerator won’t be able to cool.
To test the start capacitor:
If the start capacitor is working correctly, you should then check the thermistor. When the thermistor becomes faulty, your refrigerator won’t be able to cool, because the thermistor is responsible for sending the temperature of your refrigerator to the main control board. When it sends the wrong information, your refrigerator doesn’t work correctly.
Here’s how to check the thermistor:
The next component to check is the compressor. The compressor helps to circulate refrigerant through the evaporator and condenser coils. When it doesn’t work correctly, your refrigerator won’t cool.
Here’s how to test the compressor:
The next possible fix to the problem is to replace the temperature control board. This component helps the compressor and fan motors to operate by providing voltage to them. The temperature control board is a very unlikely cause of a refrigerator not cooling, but it can happen. Only replace it if you’ve tried every other possible fix in the article. After you replace the board, check if the refrigerator now cools properly.
If you have tried every other possible fix in this article, the last thing you can do is replace the main control board. The main control board is very rarely the cause of a refrigerator not cooling properly, so before you spend money replacing it, think about purchasing a new refrigerator instead – it might be more cost-effective.
