Refrigerator’s Common Sound/Noise-Not to be Worried

Refrigerators, whatever a new or old one, always generate some common sound/noise. As a general concept, an older refrigerator will make more noise than a newer one. Not all of the refrigerator’s common sound/noise means a faulty refrigerator. 

When we buy a new refrigerator, after that from the beginning or a few days, we can get some sound / noise from this refrigerator and due to lack of refrigerator’s common sound details, we always feel worried about it. This kind of sound / noise creates a great deal of uncertainty for us to understand the state and condition of every refrigerator. Particularly, at night, when all are in complete silence, the sound of the refrigerator can be heard loudly. In this context, anyone may think that his/ her refrigerator becomes faulty. For example, most users can not set their refrigerator location to the perfect level of the floor, and this can create a louder sound / noise.  This time users may contact with showroom or service center for this solution, after facing some hassle they can get the solution, as that, it’s just to set the refrigerators on a proper level with the floor.

Normally, older refrigerators produce more sound / noise, making it difficult for a consumer to detect the common issue and face difficulty to make a decision on the status of their refrigerator as defective or normal. For these reasons, you need to gather some knowledge of this common sound / noise of your refrigerator.

In addition, if your refrigerator makes a peculiar sound and you haven’t heard / noted before, don’t worry about it and just keep track of that sound with the correct specifics of your experience or perfect knowledge and you’ll get the answer by you own. Bear in mind that not every sound / noise you hear is not a sign of a problem, it could be a normal sound / noise. If your refrigerator is making a louder noise on a regular basis, compare it to the common sound / noise and if you find any misalignment, then you should think about repairs. It’s very important to take some time to investigate the source of any sound.

Most Common Sound/Noise Made by Refrigerator

Refrigerators often make some kind of sound/noise. Get to know the most common operating sounds /noise, maybe you are not familiar with it.

Gurgling Sound/Noise

Most common sound as it can be found in the refrigerator. 

Water/gas/other liquid flows through the evaporator, in a generic that cools the fridge/Refrigerator. As a result, it creates this Gurgling sound. This sound is especially heard just after the door is closed. 

As soon as the door is closed, water/gas/liquid starts flowing through the evaporator’s tube as well as from the trap area and this sound remains for several seconds before becoming natural.

Hissing, Sizzling Sound/Noise

Water deploying into the defrost heater after completing its defrosting cycle makes this hissing or sizzling sound. The sounds /noise also may seem like popping sounds as well.

That means water, gas, or other liquid will be moving through the Refrigerator. If you have a new Refrigerator then don’t be worried because the gurgling and hissing sound will be created more comparable than the older one. 

Just give the compressor for a few months to settle. Moreover, sometimes due to Refrigerator’s stand level miss matched with floor level, caused this type of sound. In those cases, the sound will be loudly and you need to check if the level of the fridge/ Refrigerator is matched with the stand and also with the floor.

Refrigerator’s Leveling

Buzzing Sound/Noise

Another common sound of the refrigerator. Just created for opening the water valve to fill the ice-makers. 

In detail, the compressor pumps around the Refrigerator to adjust the cooling process. When the door opens, this noise may be created by a cooling process and will take several seconds to go away.

Clicking or Tick-Tock Sound/Noise

It may be heard after power outages. This stems from the compressor trying to restart itself. 

The noise could last for 3 to 5 minutes. During the air blowing sound is ongoing, this sound can be heard when the defrost timer switches on and off.

Snapping Sound/Noise

It will be heard about 4 seconds after removing glass from a dispenser. This is the sound of the dispenser chute closing. 

In short, it happened due to Electrical control and automatic Defrost control. 

Vibration Sound/Noise

One of the most significant sounds that can be heard due to the high performing compressor. When the compressor is on and off this sound starts and ends.

Water Dripping Sound/Noise

 This sound is created for water dropping into the water drain box. Normally, you will find the outer drain box on the body side or the back of the refrigerator.

Humming Sound/Noise

Due to getting dirty on the compressor for a time being used and the condenser fan may cause a humming sound during operation.

Rushing, Blowing, and Whistling Air Sound/Noise

This sound can be heard like air blowing into the air sound. 

It’s mainly created by Evaporate fan, Condenser fan, and Condenser. When you open the door you will find this rushing/blowing or whistling sound inside the fridge / Refrigerator.

Crack and Bang Sound/Noise 

Modern Refrigerators have a defrost system. This means that heat is generated inside and moved through evaporation during the defrosting cycle.  As a result, it melts the ice and makes a crack sound.            


New or old, refrigerators often create some common sound. Refrigerators, however, produce their own functional or operating sounds almost all of the time. 

This sound often causes confusion for new users. Soon it becomes annoying a couple of days old. 

A functional or operational sound is acceptable. Knowing them, could help the user to distinguish and identify abnormal sounds. Sounds could be a warning sign for probable refrigerator’s fault. That is why we tried to give a clear concept about the refrigerator’s common sound/noise that you should not worry about.
