Samsung Fridge Not Cooling? Best Fixes

To be sure, there could be a variety of causes for the Samsung fridge not cooling issue. However, the majority of issues are minor, and many can be fixed at home by yourself. Nevertheless, for certain situations, you may need to contact a Samsung repair shop. 

Many of our readers have been sending us emails with complaints about the “Samsung fridge not cooling” issue. So we’ve created a guide detailing the possible causes and fixes for your Samsung refrigerator.

Samsung Fridge Not Cooling? Causes

There are some reasons why you might be dealing with a Samsung fridge not cooling, these include:

A Defective Evaporator Fan Motor

One of the most prevalent causes of your Samsung fridge not cooling is a defective evaporator fan motor. It is responsible for pulling cold air into the refrigerator’s evaporator coils. If it malfunctions, the fridge will be unable to chill due to a lack of cold air.

Air Damper Control

Another reason for your Samsung fridge not cooling might be the air damper control. It is a component of your refrigerator that opens and closes to allow cold air to enter the compartment. It circulates enough air in the fridge to bring down the temperature. So if you see that it is jammed shut or does not work when the refrigerator is turned ON, it may need to be replaced.

Faulty Temperature Control Board

The temperature control board is the component of your refrigerator that supplies electrical power to the compressor and fan motors. A faulty control board will not transmit signals, stopping your refrigerator from functioning properly.

Frosted Evaporator Coils

Another likely cause of your Samsung fridge not cooling is frosted evaporator coils. The purpose of the defrost heater assembly is to dissolve any ice that might have formed on the evaporator coil. So it comes up several times all through the day.

When the defrost heater assembly is not working, it causes frost to accumulate in the coils blocking them and impeding the airflow. So even if your fridge is working normally, a lack of airflow will stop it from cooling.

Defective Thermistor

A thermistor monitors the temperature of your fridge and communicates the reading to the control board. So the control board adjusts the temperature based on the readings from the thermistor. So if the thermistor is faulty, it prevents it from sending any information to the control board, which won’t be able to regulate the temperature.

Samsung Fridge Not Cooling? Fixes

Occasionally, you may need to contact a technician if the fix is too technical for you.

Fix 1: Remove Any Item Obstructing the Air Vents and Reduce the Load

Your fridge may be tightly packed with items and these items are crammed against the air vent. The air vent is at the back of the refrigerator. They allow cold air to circulate between the freezer and the fridge. So if they become blocked, the air will be unable to spread, causing it to warm up. Cold air circulation is critical to the operation of your refrigerator, so ensure that goods are spaced sufficiently apart to allow air to circulate freely

Fix 2: Check the Temperature Reading On the Thermostat

Another way to fix your “Samsung fridge not cooling” is to check the thermostat. Is the temperature above normal? If it is, then there’s no way your refrigerator is going to cool.

Fix 3: Clean the Coils

Have you ever tried cleaning your fridge’s coils? A lot of debris or dust may have accumulated all over it, especially for those who have it stationed in one position and have never moved it. Well, it is time for you to pull that fridge out and clean it.

Unplug it from the power outlet and use the hose tool on your vacuum to remove all dust behind and below it. Afterward, re-plug it back to determine if that is the cause of your “Samsung fridge not cooling” issue.

Fix 4: Examine the Door Seals

Examine the door and make sure it’s tightly closed. If there is even a tiny gap for air to escape, your Samsung fridge won’t cool properly. Or, if rubber or PVC seal is cracked, worn, or damaged, it can affect the cooling of your fridge.

Fix 6: Move Your Fridge Away From Direct Sunlight & Heat

If the position of your fridge is close to direct sunlight or a heat source, it can affect it. So try moving it away from that location. If you are unable to relocate the refrigerator, you have to reduce the temperature controls on both the refrigerator and freezer if the device is dual purpose. Don’t forget that when the outside temperature is higher, you’d need to reduce the temperature on your refrigerator.

A fridge needs to have space around and behind it to allow air to move freely and cool critical components such as the condenser.

If you’re experiencing cooling problems with your Samsung fridge, move it away from the wall. You need at least a one-inch space between them.

Fix 7: Check the Start Relay

If something is wrong with the start relay, then the compressor will not work, ultimately affecting your fridge’s cooling abilities. Get a multimeter to check for continuity between the ‘run’ and ‘start’ terminal sockets to determine if the start relay is functioning properly. If there is no continuity between the ‘run’ and ‘start’ terminal sockets on the start relay, you must replace them.
