Do you hear popping sounds coming from your refrigerator? Don’t worry about that odd popping sound; this tutorial will help you fix it.

If your refrigerator is giving you issues, try diagnosing it on your own to cut down on repair costs. It’s a terrific method to improve one’s handyman skills, too. Most of the time, the issues that lead to popping sounds can be fixed without professional help.

It’s not unusual for your refrigerator to make popping sounds. Thermodynamic expansion, refrigerant circulation, and the on-and-off operation of various parts can all contribute to this. However, popping sounds may also indicate an easily repairable issue, such as a faulty water valve or an unlevel refrigerator.

What You’ll Need

Do you really believe that repairing your refrigerator will require a whole toolbox full of specialty parts and pieces? Just use these common household items as your tools! What you need to have on hand before beginning any of these repairs is listed below.

  1. Slang term for a bubble level
  2. Pliers and drivers
  3. Spanner and nut driver

How to Fix Popping Sounds in Your Fridge

Let’s get our hands dirty and put an end to that annoying popping sound. This tutorial can be used for both troubleshooting and fixing, and we’ve organized it such that the simplest solutions are presented first.

What Should I Do if My Refrigerator Makes a Loud Popping Noise? - Soundproof Living

#1 It’s The Thermal Expansion and That’s Okay

The temperature inside your refrigerator fluctuates throughout the day. While maintaining a steady, safe temperature for your food, it cycles through several different settings. As the day progresses, thermal expansion is one of the things that can happen to your refrigerator.

When something is heated, its volume increases and the term “thermal expansion” is used to describe this phenomenon. Different materials are used in the construction of your refrigerator. Refrigerators contain a wide variety of materials, including metals, plastics, and rubbers. When heated, these materials expand in varying degrees.

There will be intermittent popping as the day progresses. This is especially possible after adjusting the refrigerator’s temperature or during a defrost cycle. This popping is completely natural and should not be concerning in any way.

It’s important to remember that even brand new refrigerators experience thermal expansion over time. It’s an inevitable byproduct of modern technology. If there are no other obvious problems with your fridge, the popping sound is likely just the result of the laws of physics doing their thing.

#2 Your Fridge Has Good Vibrations

If you hear a pop coming from your refrigerator, it may just be “positive vibrations.”

When your refrigerator is working, you may feel vibrations. The popping sounds may have been caused by the slight tremors. Vibrations in the walls of the refrigerator or the contents of the refrigerator could be to blame. The sound of two plates tapping against one other is sometimes misunderstood for a popping noise.

The majority of the time, this is nothing to worry about. There may be nothing wrong with your refrigerator other than the fact that it has finally settled into its new home and is making strange noises. Your refrigerator’s equilibrium could be wrong, causing additional issues.

Here’s how to restore equilibrium to your refrigerator.

  1. Turn off the power to the refrigerator.
  2. A bubble level should be displayed atop the refrigerator. You can use this to determine the exact level and the degree of any deviation.
  3. Take off the bottom covers of your fridge and throw them away. These grates may simply snap into place, or they may require unscrewing.
  4. It has four “leveling feet,” one in each corner, to keep your refrigerator stable.
  5. If your refrigerator isn’t sitting quite level, just move the feet around. The leveling foot has a screw or bolt that can be turned to do this. Check your handbook for details on where exactly to look.
  6. Keep an eye on the fridge’s bubble level.
  7. Once the bubble level is set up correctly from left to right, you can flip it over and do the same thing to set it up correctly from front to back.
  8. Make sure your refrigerator is level before replacing the covers.
  9. Refrigerators need to be plugged back in.

#3 The Defrost Heater

Would you be surprised to learn that your refrigerator contains a built-in mechanism that generates heat?

In order to prevent ice buildup, a defrost heater is included in every refrigerator. Fridge defrosting is the sole purpose of this heater. There may likely be a popping noise produced by the defrost heater.

About four times a day, your defrost heater should activate. Your defrost heater’s activation frequency will fluctuate depending on the day. Keep an eye out for any shifts, big or small, in behavior, as these can indicate trouble.

When the defrost heater kicks on, it makes a standard popping sound. There’s no reason to worry, and the noise shouldn’t be too much of an inconvenience. However, there may be an issue if your defrost heater cycles on and off frequently.

There could be a number of reasons for this. One possibility is that your defrost timer is malfunctioning and no longer providing instructions to your defrost heater. Another possible cause is an accumulation of frost that triggers the defrost heater to operate continuously.

A defrost heater is one of the few parts of a refrigerator that should be serviced by a professional. It’s not only cumbersome and potentially dangerous, but it requires an extra pair of hands.

#4 Sound-Alikes

Your refrigerator is prone to making popping sounds. There are numerous more sounds that may resemble popping but are in reality entirely different. Let’s talk about some of the most typical noises that could make you think your fridge is always making noise.

Your ice maker is the source of the first similar-sounding appliance. Your ice machine may make popping noises while it is either making ice or settling.

Sealing the door comes next. In order to keep the cold air inside of your refrigerator and freezer, you need to have a good door seal. Whenever a door is opened, there is usually a loud popping sound.

As an added feature, your fans can also produce a popping sound. A handful of your refrigerator’s fans can produce what sounds like popping. If the popping sounds more like scraping and/or clicking, the issue may be with the refrigerator’s fans.

#5 Water Valve Problems

This popping sound occurs frequently throughout the day and is completely normal. However, if your ice machine or water dispenser is malfunctioning, check this valve. Whenever the water valve in your refrigerator fails, it usually makes a loud popping sound.

To change it out, follow these steps.

  1. Turn off the power to the refrigerator.
  2. Find the water supply valve at the bottom of the refrigerator’s rear.
  3. You can prevent water damage by placing a towel under the water shutoff valve.
  4. Take off the cover behind you
  5. Stop the flow of water.
  6. Loosen the water line’s compression nut with a wrench.
  7. Take out the water supply
  8. The water supply valve needs to be removed from its housing.
  9. Detach the wire harness from the water supply valve
  10. Unplug the water supply valve’s wire harness.
  11. Replace the old valve by re-tightening its screws in the new housing.
  12. Join the water line to the main.
  13. Adjust the water line’s compression nut.
  14. Open the taps, please. Turn off the water supply and retighten the compression nut if a leak develops.
  15. Alternately: Switch out the rear cover
  16. Get your towel and tools in order.
  17. Connect the plug again, please

#6 Issues With the Condenser Coil

The condenser coils in your refrigerator are an element of the mechanism that circulates the coolant. The condenser coils can make a popping sound because they come into contact with heated coolant. This is quite common, and has nothing to do with any malfunctions in your refrigerator.

Why Your Fridge Keeps Making Popping Noises: 7 Steps To Fix

Condenser coils are easily accessible through the back access panel and are normally positioned in the refrigerator’s base. A problem with the condenser could be the source of a popping sound coming from the coil.

Keeping the condenser coils clean is the most important thing you can do to maintain them. Condenser coils should be dusted out once or twice a year to make sure they are not collecting dust and debris. If your refrigerator’s condenser coils are clogged with debris, the coils will have to work harder to cool your food. This can cause a lot of extra noise to be produced.

#7 Refrigerant Circulation

The normal operation of your refrigerator is the last possible source of the popping sounds we’ll discuss. Lots of fluid is always circulating inside your fridge. This substance is the coolant used in your refrigerator.

As the coolant circulates throughout your fridge, its temperature will fluctuate. It’s possible for this to result in a great deal of fluid noises like popping and gurgling. These are quite usual and ought not bother you in any way. However, if the nosebleeds become abnormally loud or are accompanied by a general inability to regulate body temperature, this may indicate a more serious issue.
