Samsung Refrigerator Not Cooling

If the first thing you noticed is that your refrigerator isn’t cooling then the problem might be a connection or power supply problem. So, as it stands, let us quickly consider some of the reasons why your Samsung fridge is not cooling.

Check Connection

Ensure your Samsung refrigerator is properly plugged into a power outlet. Remove the plug from the socket and firmly re-insert the plug. If the plug is firm, remove the plug and try another device in the wall outlet. If the new device still doesn’t work reset the circuit breaker or change the wall outlet.

Check The Door

Ensure that the door of your Samsung refrigerator is properly closed and well aligned. When the refrigerator door is open, cold air gets leaked out and warm air enters the refrigerator. This affects cooling and increases the temperature of the refrigerator.

Check Door Seal

Ensure the door seals are not torn, worn out, or dirty. A dirty or worn-out seal can cause large gaps which can let in the flow of warm air which in turn affects cooling. Clean dirty seals or frost build-up around the gasket, and leave your refrigerator for up to 24 hours to recover its normal cooling temperature. If the seals are damaged, they would need to be replaced.

Check Refrigerator Placement

When you are placing your Samsung refrigerator avoid setting it in direct sunlight or near a heat source. Ensure you change where you place your refrigerator.

Lower Temperature Settings

Lowering the temperature control setting on your Samsung refrigerator can improve cooling. The recommended temperature for a Refrigerator is about 3°C (37°F) and -18°C (0°F) for the Freezer.

Check Clearance

Move your Samsung refrigerator further away from the wall to ensure there is enough space from the wall. The minimum distance required between the back of your refrigerator and the wall is one inch.

Check Air Flow

If foodstuffs are tightly packed in your refrigerator or freezer, this may block the air vent. When the air vent gets blocked there won’t be a proper flow of air which may affect cooling. Check the air vent and ensure it is not blocked by foodstuffs.

Check Demo Mode

Ensure to check if your Samsung refrigerator was not accidentally placed in Demo mode. If your Samsung refrigerator is in demo mode, it will read OF-OF on the display. Here in this mode, the compressor is disabled to save electricity.

Generally, each refrigerator model may require a different combination of display buttons to turn off the demo mode. Some models require pressing the energy saver and power freeze or freezer buttons for 3 seconds to cancel this mode.

Samsung Refrigerator Water Dispenser Not Working

If you are experiencing difficulty with your Samsung refrigerator water dispenser not working. Try these easy troubleshooting steps before you contact a technician.

Check Display Mode

If the child lock is turned on, water will not come out of the dispenser. Hold the child lock button for more than 3 seconds to release. In case the dispenser is not locked ensure you are selecting the right button to dispense water. If the temperature is set too low, the water tank may freeze out. Adjust the temperature settings and set the temperature a little warmer on the display.

Check Water Filter 

The water dispenser may not work if the water filter is not connected or well inserted. Check if the water filter on your Samsung refrigerator was properly installed.  Check for clogs that may have reduced pressure in the water filter and ensure the water filter is locked in place properly. You can also replace the water filter to increase water pressure.

Check Water Line Connection

Check the water line connection, if you are not getting water from the water dispenser. Turn on the water supply valve to check if the outside water line is properly connected to the fridge. Check if the water supply tube is kinked or crushed, make sure you free the tube and clear it of any obstruction.

Samsung Refrigerator is Noisy or Loud

You need to understand the noise coming from your Samsung refrigerator, as this will help you to know the troubleshooting steps to take so you can easily fix this issue. Firstly you need to know that a refrigerator is never completely quiet, even if it is a new refrigerator. But the noise coming from your Samsung refrigerator ice maker or the compressor should never get too loud to the extent of interrupting a conversation. I will quickly review potential noises and the steps you can take to prevent some of the noises.

Snapping, Crackling, and Popping

A cracking noise is caused by the plastic parts of the refrigerator which expand as the temperature of the refrigerator rises and falls during the defrost cycle. This is a normal sound for all types of refrigerators, and it fades with time.

Buzzing and Humming

If a water line is not connected to your Samsung refrigerator model, turn off the ice maker to avoid this sound and to prevent damage to your refrigerator.

If you have a water line connected, you will hear the sound of water filling the ice maker. This noise can get louder when the pressure gets higher. Try to reduce water pressure.

These sounds may also depict the sound of the compressor. It will start running at a low speed before it moves to a high speed. When it changes speed, the compressor may make some clicking as it operates. When the fan slows to a stop the compressor may sputter.


When the temperature in the refrigerator is high, it may beep with a blinking display and this often occurs due to a power outage. Ensure you correct the cooling issue to resolve the beeping sound. Also when the door of your Samsung refrigerator is not properly shut this will trigger the alarm system. Ensure nothing is blocking the door and ensure it is tightly closed and aligned.

Blowing and whistling

This type of sound is from the circulation fans of your Samsung refrigerator. To fix this, slightly reposition the refrigerator, and leave about 2 inches of clearance on the top, sides, and back.

Hissing, Bubbling, Or Gurgling

As refrigerants move through the cooling system, it changes from liquid to gas and back forth. You may hear a gurgling or bubbling sound during this process. Also when water drip onto the defrosts heater, it makes a hissing or sizzling sound.


When ice falls from the ice maker into the bucket you would hear a loud banging sound.


When ice is dispensed or when crushed ice is selected you would hear a grinding sound made by the refrigerator ice maker. This sound is from the motor that pushes the ice forward.


You may hear a squeaking sound if you have a squeaky door hinge. Ensure the door was reinstalled properly if they were removed and put back. Also, ensure the leveling legs are in full contact with the floor and the wheels are not touching the floor at all.

Fan hitting ice

This type of noise is from the buildup of ice around the fan. You can service and perform a manual defrost to clear the buildup of ice and get rid of the noise.


The rattling sound can be from something banging the refrigerator from behind. Move your refrigerator an inch to see if that stops the noise. The rattling sound can occur for a couple of moments when the compressor turns off, as it putters to a stop.

These Samsung refrigerator repair steps should go a long way but in case these easy fixes don’t solve your Samsung refrigerator repair problems then you can request service or call a technician.
