Fridge Sounds Like Water Gurgling. Here’s Why?

A refrigerator will emit a variety of noises when it is operating. You might hear sounds like this, such as bubbling or gurgling. You might consider it so unusual that you start to wonder if it still constitutes a standard element of your refrigerator’s everyday operation or if it is already an indication of technical failure.

Thankfully, the gurgling sound coming from your refrigerator is very typical. The Freon in the refrigerator is making the noise you’re hearing, which shouldn’t be a cause for alarm. We’ll talk about why a refrigerator generates this noise in this article and why you shouldn’t worry about it.

The only sound you ever want to hear from a refrigerator is a consistent hum, indicating that it keeps your food cool as it should be. However, a gurgling sound coming from your refrigerator could mean a problem. 

You should be concerned if you notice any changes in how your refrigerator operates, including an odd sound, as these machines are costly to replace. Fortunately, a gurgling sound does not necessarily mean a significant problem.

What Causes A Refrigerator To Gurgle 

Fridge Sounds Like Water Gurgling

It’s common to hear some gurgling as a refrigerator settles. To cool down its compartments, a refrigerator uses the power of evaporation. This is accomplished by the refrigerator’s internal copper tubes continuously undergoing evaporation and condensation of the refrigerant gas (Freon).

The Freon begins as a liquid, but after being pumped through the expansion valve of the refrigerator, it loses a lot of its liquid state. The cooling effect of the fridge is caused by the evaporation of this boiling liquid, which finally converts into gas.

By now, you should have guessed that the gurgling and bubbling sound you hear while your refrigerator operates is typically caused by boiling Freon. 

Fun fact: Although the Freon appears to be “boiling,” it’s not that hot. The boiling point of R-134a, one of the most used refrigerant gasses for refrigerators, is -26°C, far lower than the boiling point of water, which is 100°C.

Defrost Heater Coming Into Contact With Water (no frost models) 

To remove the frost from their freezer, no-frost refrigerators include a heating element hidden behind the freezer’s walls. When water drips into the heating element, a hissing, sizzling, or gurgling sound may be made. That is typical. 

An Overflowing Drain 

The melted frost is directed out of the refrigerator by a drain pipe. The water rushes out of the drain hole and occasionally makes an odd bubbling and gurgling sound. This is typical.

Water Supply Line Leaks

You should confirm the water supply line for spills or damage if your refrigerator is making gurgling noises. There might be a liquid pool on the ground. When bringing in fresh water, the fridge may gurgle if the air is drawn into the water line. You can either replace the defective hose or get assistance from a specialist who repairs appliances.

The Gurgling Sound of Refrigerant Flow

Place your palm on the refrigerator’s door or side to detect a faint vibration. This is possibly the compressor working on the liquid refrigerant. It’s typical for the refrigerant to gurgle as it flows through the system.

Making fewer trips to the fridge is an easy way to lessen this noise. Because hot air is let in when the door is opened, the compressor must work harder (and use the refrigerant more) to cool things down again.

Defrosting Cycle Melted Water

If you hear water trickling and gurgling in the freezer section, wait until the refrigerator has finished its defrosting cycle. When the heating coil is activated, the melted water from the frost runs down to a drain pan where it can evaporate.

The defrosting procedure typically takes 30 minutes. In most refrigerators, this happens automatically and cannot be stopped. Try to avoid unneeded frost development by keeping the doors closed.

Air Gurgles in the Drain Tube

If the water in the refrigerator gurgles when you shut the door, wait while it equalizes. As a result of air being driven into the drain tube, this is natural. Although the gurgling may continue for a few seconds, it should eventually stop.

When the humidity is high, which happens more frequently than when the humidity is low, you can hear the drain tube gurgling.

How To Permanently Quiet A Gurgling Refrigerator

Fridge Sounds Like Water Gurgling

As the “heart of the house,” your kitchen should be an inviting space where you can unwind. A noisy refrigerator severely hogs your family’s enjoyment of cooking, serving, and enjoying meals together in this common area. And to make matters worse, the noises it is producing can be a sign of a significant issue.

Do not put off taking action until your refrigerator becomes inoperable or breaks down completely. Read on to learn how to permanently silence a noisy refrigerator, from completing your own research to contacting experts.

Locate the source of the noise

The source of the sounds coming from your refrigerator is a significant clue as to any potential problems. Before trying to get to the various places and parts, it is essential to turn off the power for your safety.

Sounds coming from behind are probably one of the following:

Condenser fan: In some instances, this problem can be resolved using a soft brush to remove collected dust and debris.

Compressor: It could be necessary to replace a noisy compressor.

Defrost timer: A loud defrost timer must be returned in most cases.

Even while it would be acceptable to clean the condenser fan by yourself, you should always leave part replacements to the experts.

If the sounds originate from the interior of your refrigerator, a different culprit will be involved. Most likely, the fan is in charge of moving air through the fridge and freezer.

Therefore, it is crucial to get it rectified if it has to be repaired. By depressing the light switch in the freezer, you can decide for yourself. The fan has to be replaced if the noise level increases.

Frequently Gurling Refrigerator Components

Although there are various components in your refrigerator, a few tend to cause noise. The first step in determining how to quiet a noisy refrigerator compressor is identifying the component that needs to be repaired. If the noise emanates from the compressor, it might be from the condenser fan. To make this judgment, unhook the fan’s motor, plug your refrigerator back in, and listen to see if the noise persists without the fan running. If it does, this suggests that your compressor might be broken.

The freezer is where you’ll find the evaporator fan. A qualified expert should investigate this potential problem because it entails opening the interior panel. Clips or screws are frequently used to block off this space. The latter may need to be removed with a screwdriver. After gaining access to the panel, the repairman will check the fan blade, wiring, grommets, and other parts for wear and tear.

Remember that while you can perform some simple activities on your own, it is recommended to leave the majority of refrigerator noise troubleshooting to skilled professionals with the necessary experience and knowledge. Always prioritize your own security and the security of your loved ones.

What Is Typical And Abnormal Regarding The Sound Of The Refrigerator?

Fridge Sounds Like Water Gurgling

Normal noises that a refrigerator makes include:

  • A fan’s speed noise. When you often open the fridge, it changes due to the temperature response.
  • A bubbling or gurgling sound is made when the refrigerator is operating.
  • Strong rubber seals on the refrigerator door edges cause a squeaking or chirping sound to be heard when you open and close the door. The sound fades away after prolonged use.
  • There is a ticking sound when the defrost turns on or off.
  • When the ice maker has more water, there is a humming sound.
  • Automatic defroster that emits a water-like sound
  • Ice cubes falling into the storage bucket make a loud noise.

The Unusual Noises A Refrigerator Makes

  • Making rattle noises could indicate that some of its functions are broken.
  • The dripping noise can be a sign that the refrigerator has a leak.
  • A sound emanating from the refrigerator’s back resembles fan blades striking an object.
  • Although compressors typically produce a modest buzzing sound, if the sound increases, there may be a mechanical problem.
  • Last, a water leak or puddle outside the refrigerator will prevent it from cooling or making noise.


The melting frost exiting a refrigerator through a drain pipe can make some noise amongst other things. A strange bubbling and gurgling sound occasionally emanates from the drain hole when water is rushing out of it. Additionally, this is typical. The crackling sound your refrigerator generates is typical of how it works. It is not at all something to worry about.
