Modern refrigerators operate soundlessly, and any sound emanating from them might come as a big surprise.
It is true that LG fridges do not run much into trouble, but like any other electrical appliances, there is always a chance. And, one of the most common problems that you might encounter is the device making noise. At times, the sound can be pretty normal. And, at other times, it might be an indication to call for repair service.
When you are tired of your LG refrigerator making noise, it is best that you go through this guide to understand what is causing the problem. Once you decipher what’s the problem, you can opt for the best ways to fix it.
So, let’s dive in!
Reasons For A LG Refrigerator Making Noise And Possible Solutions
1. Buzzing Noise Coming From An LG Refrigerator
When you hear a low-pitched buzzing noise from your LG refrigerator, there is nothing to worry about. This sound is mostly generated by the compressor whenever it is switched on. However, when the buzzing sound turns into a loud noise, you might have a problem.
In this context, it is important to note that LG refrigerators mainly come with two types of compressors. Yours might have the standard compressor that generates a low hum when it is functioning. As this compressor does not change its speed, the buzzing sound is constant.
On the other hand, your LG refrigerator may also come with a linear compressor that works in accordance with the cooling needs of your fridge. Unlike the standard compressor, the speed of a linear compressor may change when the activity inside the fridge increases. And, this might produce loud noises.
However, if you notice that there’s too much noise coming out of our LG refrigerator, you need to do the following things:
Steps To Follow:
To fix this issue, start with removing the top panel of your refrigerator. Once you do that, check if the condenser fan motor is properly connected. If you see a problem here, disconnect the wires before reconnecting them again. While you are at it, also check if the plug is connected to the right socket.
Once you are done with these steps, turn off the power switch and let your refrigerator rest for ten minutes. After that, you can switch it on and by this time, the buzzing noise from the compressor should no longer be present.
In case the problem persists, it means that this quick fix won’t work! And, to ensure that your refrigerator works properly and there is a steady flow of cold air, you will need to call a professional electrician.
2. Popping Noise From LG Refrigerators
If you hear a popping noise emanating from the refrigerator, there is no need to lose your head over it. This mostly happens when the walls inside the refrigerator unit contract or expand. Whenever the internal temperature in the appliance changes, there will always be a chance that you will hear popping noises.
Unless it is too loud, do not try to stop the popping sound as it is a part of the normal functioning of all fridges. The sound might also come from the refrigerator door. In case the door cam is malfunctioning, there will be a loud popping noise every time you open or close the door.
Also, when the evaporator fan and coils get cooled after the defrost cycle is over, you might hear loud popping noises. To fix this problem, we suggest that you keep the fridge switched off overnight and turn it on in the morning. This will clear all possible debris that might be blocking the normal functioning of the fridge.
In case the problem is still not resolved, it is best that you take professional help.
3. Noise Coming Out Of The Ice Maker
Three out of five times, an LG refrigerator ice maker makes noise because of the frozen water valve. When this valve is frozen, it gets difficult for the water in your fridge to get into the ice mold. And, because of that, you might hear noises coming from your fridge.
If you hear a clicking noise from the ice maker, your first order of business should be to defrost the water valve. You can either use the defrost heater or use the manual way of defrosting the fridge. For that, you will have to unplug the refrigerator from the power source and remove all food items from the appliance.
We suggest that you leave the LG refrigerator door open for a few hours to ensure that the defrosting happens appropriately. After you are done with the process, the ice maker should function normally without making any clicking noise.
Noises from the ice tray might still persist if you fail to close the ice bin door properly. In that case, it is best that you first open it and then close it again. Unfortunately, if the problem still does not get fixed, it is best that you first remove the ice tray and clean the ice bin area.
Also, ensure that the water supply line to the tank is clean and not covered in grime and debris to avoid noise.
4. Refrigerator Making Beeping Noise
You will hear beeping noises from an LG refrigerator, mainly when it is trying to alert you about something. For example, when your fridge door is kept open for too long, you might hear the door alarm go off. So, whenever you hear a beeping noise coming from the fridge, you should first check if the door is closed correctly or not.
If your refrigerator is still making noise even after shutting the door properly, there is a chance that the gasket needs to be cleaned. Whenever the gasket becomes dirty, it does not allow the fridge door to seal completely. And, because of that, the fridge gets the wrong signal that it is not entirely shut.
So, to ensure that the cooling system is functioning properly and your fridge is not making any noise, it is essential that you clean the gasket from time to time.
We suggest that apart from keeping the gasket clean, it is crucial that you check the content arrangement in your fridge. If the door switch is getting blocked because of the contents, you might end up with a noisy refrigerator.
5. Noisy Fan Blades
In case there are loud noises coming from an LG refrigerator fan, you need to check both the evaporator fans and the condenser fan.
Start by checking the fans present in the freezer to see if the blades are turning properly. If you notice obstructions, there might be the presence of debris, and you will need to clean that. To treat the issue properly, you will have to oil the blades. If things still do not get fixed, you might need to replace the fan blades.
Next, you should proceed to check the condenser fans. To make sure the fans spread cold air evenly and there is no loud noise coming from the refrigerator, check if the condenser fans are spinning freely.
When there is a faulty fan or motor, your refrigerator won’t be able to cool the compressor and coils or evaporate water from the drain pan. In case any of these two fans are damaged, they won’t circulate air properly and will surely make a lot of noise.
6. Humming Noise From An LG Refrigerator
You might often find a humming noise coming out of the refrigerator, and this mostly happens when the motors malfunction. There can be a problem with the belt or a case of broken blades. However, dealing with this issue is simple. You will need to tighten the belt and replace the fan blades if they are damaged.
In case the condenser in your LG refrigerator is not functioning optimally, you might hear a humming sound coming from it. If the condenser is malfunctioning, it will hamper the cooling in the fridge and might also generate noises.
To fix the problem, open the fridge door and begin with removing the back panel. Once the back panel is opened, disconnect the wires to the compressor and reconnect them. This should get the problem fixed. In case the problem persists, you will need to get professional help.
7. Issue Of Gurgling Noise
Mostly, you get to hear a gurgling noise coming out of an LG refrigerator when the refrigerant flows through the cooling system. So, you can understand that this is a part of the regular operation of the fridge, and you should not be too worried about it. Unless, of course, the noise is very loud! If the noise bothers you, we are here to tell you how to muffle it.
The most efficient way to deal with this problem is to reduce the number of times you open the fridge door. If you open it too many times, the compressor has to put in extra effort to keep the refrigerator cool. This simply means that it has to put more effort into compressing the refrigerant, giving rise to the gurgling noise.
Apart from that, a gurgling noise can arise from a malfunctioning water inlet valve and drain line. And, humidity inside your fridge can also cause this sound. If the issue is with the water valve, you can fix the problem in a jiffy.
Begin with opening the valve to improve the water flow. In case the flow of water from the valve to the ice maker is restricted, you might hear a gurgling sound. If you notice that the water line is leaking, it is best to replace it.
Apart from that, when the fridge enters the defrost cycle and starts to drain water, you might hear some noises.
8. LG Refrigerator making Hissing Noise
You might notice that there is a hissing noise coming from your fridge. We have noticed that this mostly happens during the defrost cycle. It is during this time that the ice melts, and water drips on the defrost heater. This is what gives rise to the hissing sound.
There is no need for you to worry when you hear this noise, as it is pretty normal during the defrost cycle. However, if you notice that the sound continues even after the defrost cycle is over, there might be something wrong with the appliance.
At other times, you might even hear a hissing noise coming from the compressor. In that case, it is best that you unplug the appliance from the power source and keep it switched off overnight. This will enable proper air circulation and help clear any unwanted debris that might have collected over time.
Plug the fridge into the power source in the morning, and the hissing sound should no longer be there.
9. Banging Noise From An LG Refrigerator
To ensure that your fridge does not make a banging noise, the first thing that you need to do is place the appliance away from the wall. This noise is very common when you place the machine very close to a wall or a piece of furniture.
Typically, a refrigerator vibrates a little when it’s turned on. So, when it is running, this vibration may lead it to touch other nearby surfaces, giving rise to a vibrating noise
In order to avoid this problem, it is best that you leave some space between the refrigerator and the wall. This will not only prevent the knocking or banging noise but will also make your fridge last longer. That said, the fridge being close to other surfaces might not be the only reason behind the banging sound.
The problem might also arise from a malfunctioning evaporator fan or condenser coil. And, in older LG refrigerator models, banging sounds may occur in case the compressor is not functioning correctly. In case the condenser fan is clogged with dirt, its movement gets obstructed and gives rise to the banging sound.
10. LG Refrigerator Noise Stops When Door Opens
If you notice that the noise stops every time you open the freezer door, there is a good chance that the evaporator fan needs fixing. Sometimes, you may find ice build-ups around the fan blades. And, this can lead to loud noises coming from your fridge. At other times, the noise may be generated because of a faulty motor.
However, every time you close the door, the noise might resume. To understand if it is the fan that is giving rise to the noise, we suggest that you open the freezer door and inspect the situation properly. In case you notice the noise stops every time you open the door, it is best to get the fan replaced.
The motor gets back in action as soon as the door switch activates, and because of that, the noise continues whenever you close the door. Once you inspect the fan condition, you will know whether it needs defrosting or not. If you notice that there is no ice build-up around the fan and it is still making noise, the best solution is to get a replacement.
11. Problem Of Chirping Noise
When you hear a chirping noise from the refrigerator, it might be because the fan motors are malfunctioning. We have seen that in most cases, it happens when the evaporator fan is not working to its full capacity.
To locate the noise, move close to the freezer section. If you notice that it is the source of the sound, open the freezer door and remove the back panel. After that, you will need to disconnect the wire harness that holds the fan to the panel and separate the two.
We suggest you use a multimeter at this stage and check for continuity. In case the fan motors are damaged, you will see no continuity on the multimeter. If that is the case, you will need to get the motor replaced soon.
However, you might be in a situation where you see that the sound is not coming from the freezer. Then, you will have to check the damper control, which you will find above the fresh food section. A broken damper may give rise to a chirping sound, and it is best that you get it checked too.
12. LG Refrigerator Making Rattling Noise
Rattling noise from an LG refrigerator might arise when the water supply line is not fixed tightly. To check if it is in proper condition, you will need to take a peek at the water line, which runs along the back of the refrigerator.
As we have already mentioned, in case there are items or furniture around the fridge, the normal vibrations of the appliance can give rise to a rattling sound. The same might happen if you keep objects on top of the refrigerator.
If there are no issues with any of these factors, there might be other problems, like an uneven floor or a malfunctioning drain pan. To deal with the problem of uneven floors, you will need to level the floors first. However, if that seems too much of a task, you can consider moving the refrigerator to another room.
Coming to drain pans, it often happens that the bracket that holds it in place becomes loose. This makes the pan rattle every time the refrigeration cycle goes on and off. To deal with this issue, get your hands on a screwdriver, and secure the pan properly.
13. Grinding Noise From LG Refrigerator
You might hear grinding noise coming from your refrigerator if there is an ice build-up around the evaporator fans. If you notice that the sound is coming from the freezer, then you will have to open the freezer section.
There is a good chance that you will notice that the sound will increase before finally coming to a stop. That means that the evaporator fans are malfunctioning and the blades are getting obstructed. To solve this issue, you will have to unmount the rear wall of the freezer and check the fan.
If you notice that there is ice build-up around the fan, you will need to defrost it. To do this, you can use a dryer to melt the ice or put the fridge in manual defrost mode. And, we suggest that you prefer manual defrost. To do that, you will have to keep the fridge switched off and remove all food items from it.
In order to make things easier, you can place multiple clothes around the fridge to ensure that your floor does not get flooded when the fridge defrosts.
14. Noise Coming From Refrigerator Door
Sometimes, it might happen that the door lock is malfunctioning or the door cam is broken. In case these fittings are damaged or worn out, there is a good chance that your refrigerator is getting the wrong signal that the door is not shut correctly.
In the case of a worn-out cam, it is best to replace it. That way, the fridge will not make any noise after you shut the door. However, there can be other reasons behind your fridge door making a sound and you should inspect it carefully.
With that, it’s a wrap!
We hope that after reading this guide, you are better equipped to troubleshoot the problem efficiently. After a few months of using it, your LG refrigerator might run into trouble and make noises. In most cases, it simply is an indication that your fridge has a malfunctioning part.
But, with a better understanding of the noises, you will be able to identify when it is normal and when it’s a cry for help. If you know that your fridge has run into a problem, we suggest fixing it at the earliest. For people with limited electrical skills, it is best that you take advice from a professional or simply give a call to the nearest LG service center.
Until next time, take care!
