Samsung makes a huge array of appliances known the world over. From televisions to washing machines and just about any kind of kitchen appliance, they have become a trusted name within the appliance industry.
Their line of refrigerators, though considered reliable, can experience issues from time to time. You may notice a weird noise from time to time that stops when you open the refrigerator door. This is likely due to ice that is built up around the fan. Performing a defrost is the best way to get rid of both the ice and the noise.

What is That Noise and Why Does it Suddenly Stop?
You may hear a noise that sounds similar to a grinding noise. This sound is quite common in Samsung fridges as there is a common issue at play. The most common cause is a build up of ice around the refrigerator’s fan.
When the refrigerator door opens, the fan stops, stopping the noise along with it. The only solution is to manually defrost the fan to get rid of both the ice and the noise. Keep in mind that a manual defrost is a temporary solution and the sound will come back. Only a service call can truly resolve the original issue without the noise coming back.
How Do I Manually Defrost my Refrigerator’s Fan?
It is possible to perform a manual defrost on your Samsung refrigerator’s fan. Before performing a manual defrost, it is essential to note that you should never use a hairdryer or other heat source. Doing so can potentially damage the refrigerator, leaving you with a far larger and more expensive issue than you started out with.
- Empty the fridge. Start by taking out any perishable food items and emptying any ice buckets within the fridge. It could take some time to implement the defrost and you don’t want food going bad in the meantime.
- Lay down towels. Put down a layer of towels underneath the fridge. Make sure that you keep some handy for any potential leaks that may occur. Clean up as you go and it will be far easier to keep things from getting out of hand.
- Unplug the fridge. Remove the plug from the wall to cut off the power to the fridge. Then, prop the doors open so that you can work without restriction.
- Swap out towels. The fridge will need to defrost naturally. As it does, water will get out, soaking into the towels. Remember those extra towels? They will come in handy here to swap out so that the towels on the floor don’t become sopping wet. Keep replacing the towels until they stop becoming wet or until at least 24 hours have passed.
- Turn the fridge back on. When you feel confident that the defrost process has completed, close the doors and turn the fridge back on. Give it about 2 hours to ensure that the thawing has happened before putting any food back in the fridge.
Common Refrigerator Noises
The aforementioned sound is not the only one that may emanate from your Samsung fridge. There are plenty of other sounds that require troubleshooting to get to the bottom of the issue. Rattling is one such sound.
You may notice that there is a rattling sound coming from behind the fridge. Try to move the fridge out about an inch to see if that resolves the issue. The rattling generally happens when the compressor is turning off. The rattling should lasts 10 seconds or so before quieting. If it doesn’t stop, you may need to make a service call to find the issue.
It is not uncommon for refrigerators of all kinds to have squeaking noises. The most common cause of that squeaking is a door hinge. There are fixes for both new/unused fridges as well as those who have years of use behind them.
- Proper reinstallation. If the refrigerator doors were taken off for any reason, there is a chance that they were installed improperly. Check to make sure that the refrigerator doors are seated properly. You can follow the instruction manual for detailed instructions on reinstallation.
- Leveling legs. When you look under the fridge, you should notice that the leveling legs are in full contact with your floor. Moreover, the wheels should not touch the floor in any way. You can try leveling the refrigerator to see if that resolves the squeaking issue.
- Give it time. Let the refrigerator run for a week or so. There is a chance that the harness running through the door might not be seated properly in a new refrigerator. The more the doors are opened and closed, the better the chance the harness will seat properly. If the noise persists after a week, take the hinge cover off and check out the wire harness, reseating if necessary.
- Spray the hinges. On older refrigerators, you may need to spray the door hinges. It is important to not use WD-40 since that will remove the grease that is around or in the hinges. Go with a food-grade silicone spray instead.
In modern fridges, like Samsung’s line, beeping is used to indicate a door that is ajar. The purpose of the beep is to keep your food from spoiling, the compressor from working overtime, and your energy bill from getting run up. There are several things that may be at fault when the refrigerator beeps even when the doors have been closed.
- Temperature too high. If you notice that there is a beeping or a blinking display, it could be an indication that the temperature in the fridge is too high. In the event of a power outage, this can be a normal thing. Correcting the cooling issue will resolve that beeping noise.
- Door ajar. Even if you think that the door is fully closed, that may not be the case. Open the refrigerator door and close it again to ensure that it is not ajar.
- Connecting the wire harness. When the doors are removed and then reattached, they may not seat properly. If you hear beeping even when the doors are closed, try connecting the wire harness properly.
- Look for other sources. It could simply be that you are hearing beeping from somewhere other than the refrigerator. When there are other appliances in close proximity, it can sound like there is a beeping coming from the fridge. Verify that the beeping is coming from the fridge before implementing any troubleshooting methods.
Humming and Buzzing Noises
The most common source of buzzing and humming noises has to do with the ice maker. If your water line isn’t properly connected, simply turn the ice maker off. It should avoid any potential noises and unwanted damage to the refrigerator.
Waterline. When the water line is connected, you may notice a much quieter humming or buzzing noise. That is actually the sound of the ice maker filling with water. When the pressure is too high, the noise can be much louder. Turn down the pressure if you want, just make sure that it can still fill a cup ¾ of the way in 10 seconds.
Compressor. If the water line or ice maker is not the culprit, you may be looking at noises coming from the compressor. The compressor sounds akin to a fairly quiet motor or engine. When it starts up and runs at one of the designated speeds, you may hear a clicking noise. When the fan slows down to a stop, you may hear a sputtering noise.
Popping, Snapping, and Crackling Noises
There are plastic components within your Samsung refrigerator that expand and contract depending on the temperature of the refrigerator. If you hear cracking noises coming from the refrigerator, you are likely hearing that expansion and contraction.
Defrosting cycle. The most common time for those popping and snapping noises is when the refrigerator is in its defrosting cycle. The problem also tends to be a common one with new refrigerators since they are acclimating to the humidity and temperature levels in the home. The sound should fade over time as the refrigerator adjusts.
Noise levels. When there are no other underlying issues, the volume is similar to putting ice cubes into a warm drink or even the cereal Rice Krispies. The sound might be a little louder since the fridge is much louder than those things, but it should still be relatively quiet on the whole.
Bubbling, Gurgling, or Hissing Noises
Though they are far less common than the aforementioned issues, you may hear a gurgling, hissing, or bubbling noise. These sounds are indicative of refrigerant moving and changing through the cooling system. It changes back and forth between a liquid and a gas, creating those noises.
Another common cause for these noises is water dripping on the defrost heater. The cold water hits the warm defrost heater, creating a sizzling or hissing sound in the process. Dripping is normal, it is when that dripping evolves into a leak that there is a problem.
