Why Samsung Fridge Is Not Cooling? First Troubleshooting Steps To Take

Samsung fridges are “notorious” for having problems with Twin Cooling Plus technology, along with evaporator fan and compressor failure. 

But the main reason why Samsung fridge is not cooling PROPERLY, in most cases caused by ice or frost build-up that restricts air circulation in the fresh food compartment. This build-up, on the other hand, can be caused by a defective defrost heater, clogged drain line, failed defrost thermostat, bad evaporator fan, or defective defrost temperature sensor.

The other reason why Samsung refrigerator is not cooling AT ALL in both freezer and fresh food compartments is caused by a failed compressor inverter board, a bad compressor, a refrigerant leak in the sealed system, or a restricted drier filter.

The evaporator coils are frosted over:

When the evaporator coils get covered with frost, the evaporator fan is unable to circulate cold air within the fridge due to blockage, and the fridge will not cool. This problem is related to failed defrost cycle.

Sometimes, the problem can be solved by replacing the defrost temperature sensor (but it does not always fix the problem)

There are actually 2 identical temperature sensors. But you will need one with the white connector on the right side of the fridge.
