You’ve made an excellent choice in buying a quality refrigerator. So why is your Samsung refrigerator not cooling? There are several reasons this may occur. Some problems you can fix yourself, while others may require a Samsung Factory Authorized technician to diagnose and repair.

7 Reasons Your Samsung Refrigerator Won’t Cool

From simple issues with food organization to more complex problems with your refrigerator’s evaporator, this list will give you insight into the most common causes for why your Samsung refrigerator won’t cool.

The Basics

Before you call for service, it’s a good idea to check some of these common consumer causes for a refrigerator not cooling.

  • You have the food packed too tight. Your refrigerator needs air flow! If you have too much food stuffed in the refrigerator or freezer, you may be blocking an air vent, which will cause your refrigerator to not cool as well as it should. Check that your air vents aren’t obstructed by food.
  • The temperature was accidentally adjusted. Hey, it happens from time to time. Double check your temperature settings to make sure someone didn’t turn up the heat! The Samsung refrigerator should be set at or below 40 degrees F. Your freezer should be 0 degrees F.

Door Ajar

The best solution is sometimes the most overlooked one. The next thing to check when you notice your Samsung refrigerator won’t cool is the door. It just takes one careless or hasty food browser to not close the door completely to cause the temperature to rise. If the door was ajar, give the refrigerator several hours to regulate back to the correct temperature.

Door Seals

The door seals are a critical component to keeping cold air trapped inside the refrigerator and warm air out. Check to make sure the door seals are not torn, weathered, or dirty. Dirty seals can cause gaps large enough to let in warm air, which affects cooling. If you notice dirty seals, clean them immediately, and allow your refrigerator up to 24 hours to regain proper temperature. If the seals are damaged, service will be required.

The Evaporator Coils are Frosted Over

The evaporator coils are a key component to keeping the refrigerator cold. While air from the refrigerator blows over the evaporator coils, the liquid refrigerant inside the coils absorbs heat from the air, blowing it back into the refrigerator at a lower temperature. Sometimes, frost will develop on the evaporator coils. If the evaporator coils are frosted over, the airflow through the coils is restricted, which will mean your Samsung refrigerator won’t cool. Check the evaporator coils to see if they are covered with frost. If you find frost, test each component of the defrost system, beginning with the defrost thermostat.

Defrost Thermostat

The defrost thermostat monitors the temperature of the evaporator coils. When the coils drop below a set temperature, the thermostat initiates the defrost cycle, where the defrost heater dissolves any frost that has accumulated on the evaporator coils. If the defrost thermostat is defective, the defrost cycle never kicks in. Use a multimeter to test the defrost thermostat for continuity. If the defrost thermostat does not have continuity when it reaches the low temperature of its operating range, replace it.

Evaporator Fan Motor

The evaporator fan motor draws cold air over the evaporator coils and circulates it throughout the entire unit. The refrigerator won’t cool adequately if the evaporator fan is not working. Try turning the fan blade by hand to see if it will turn freely.  If it does not turn freely, replace the fan motor. Additionally, if the motor is abnormally loud, or not running at all, it’s best to replace it. You can use a multimeter to test the motor for continuity, and if you don’t confirm continuous operation, replace the evaporator fan motor.

Damper Control Assembly

The air damper control opens and closes to let cold air into the refrigerator. If the damper does not open properly, it won’t let enough cold air into the refrigerator. Check the damper control to determine if it is broken or stuck closed. If it is hindered, replace it.
