Why Is My Fridge Making a Buzzing Noise?

Before you go ahead and start fixing that buzzing noise from your refrigerator, it’s important to understand why your fridge is buzzing.

Here are a few reasons your fridge could be making noise and what you should do in those cases.

If all is good, you can move on to tips on how to stop refrigerator from buzzing.

So what refrigerator parts can make noise?

Compressor

The compressor is located at the back of the refrigerator. It will make a constant buzzing or humming noise.

This sound is normal. It operates when it tries to cool down the refrigerator, which is practically…all the time.

There can also be dripping sounds coming from water dripping into the fridge drain pan during the defrost cycle. The drain pan just needs regular cleaning, and you should be good to go!

A low buzzing noise is normal, but if it’s an unbearably LOUD NOISE, then consider calling a technician.

Something you can do to keep that noisy refrigerator compressor from making these noises is to do regular maintenance.

Condenser Coils

When the condenser coil is covered in dust, it will overwork trying to cool down the inside of the fridge. This causes it to make a loud buzzing noise.

To avoid this, you want to clean the condenser coils regularly. You can do this yourself by VACCUUMING it. But if it’s not easily accessible, it would be best to call a professional to do regular fridge maintenance and cleaning for you.

Condenser Fan Motor

If the fridge is making an overly loud sound, the condenser motor fan could be the culprit. In this case, cleaning the condenser fan motor is your top priority.

Ice Maker

If your fridge has an ice maker, this could be the source of rattling noise.

Built-in ice makers would make a low-level noise while making ice cubes. If the sound is LOUDER than usual or if there are noises while ice is not being made, then you will have to get your noisy fridge serviced.

Defrost Heater

This could be the culprit of any hissing noises being made. This is no worry, it’s normal. The sounds may seem scary, but it’s simply water dripping on it.

Drip Pan

The drip pan is located directly beneath the refrigerator. It can make quite annoying water-dripping sounds but don’t worry; this is completely normal.

To keep the drip pan from making this noise, just make sure you clean it regularly.

Water Lines

This can cause your fridge to make a gurgling noise or rattling noise. This is just the water lines moving against the refrigerator.

So if you find your fridge making rattling noises, there’s nothing to be worried about. It’s just water lines. 

Freezer Compartment

Noise coming from the inside of the freezer can be ALARMING. And you are not wrong at all to think this.

If your freezer is making a loud buzzing noise, then the evaporator fan is probably damaged. You can check this by removing the fan cover and visually inspecting the evaporator fan motor.

In this case, you may want to have your refrigerator fixed.

Defrost Timer

Many modern refrigerators have defrost timers.

If you hear ticking noises, then you might a faulty defrost timer. In this case, it’s best to have it replaced ASAP.

Tips on How to Stop Refrigerator From Buzzing

Now that you know the cause of your refrigerator’s noise, it’s time to quiet your refrigerator.

Here are some tips on how to stop refrigerator from buzzing.

Tip #1 Get Rid of Floor Vibrations

The first step on how to stop refrigerator from buzzing would be to make sure your refrigerator isn’t sending vibrations into the floor.

If your fridge is not level, it will make a vibration noise, which sounds a lot like buzzing bees.

What Should You Do?

All you have to do is to make sure your refrigerator is on a flat and level surface.

  • If the appliance is already on a flat surface, you’ll want to make sure the legs of the fridge are even. The legs of a refrigerator are often adjustable. So make sure they’re adjusted properly!
  • If everything looks good in this aspect and your refrigerator is STILL buzzing, then no worries! You can put thick rubber mats under the fridge. This will help absorb any vibrations coming from the fridge.

You know what would be PERFECT for this? Anti-vibration mats. So if you can invest in those, we suggest you DO IT. It will make a significant difference and stop any buzzing noise.

Tip #2 Clean the Evaporator Fan Motor and Compressor Coils

Refrigerators require the use of a motor and compressor to work and cool properly. When the condenser fan motor coils are covered in dust, it will overwork to cool your fridge.

The coils are located at the BACK of your fridge.

Regular maintenance for your refrigerator is how you can keep your fridge quiet.

If the noise is coming from the compressor, then it’s most likely dirt and dust causing the noise.

The Solution?

Keeping the compressor and fans clean is the way to go.

Unless you are a professional or KNOW YOUR FRIDGE VERY WELL, then you will want to get your compressor serviced by REAL professionals.

This method can significantly reduce the noise. You can even have it checked for other issues that may be present.

If, for any reason, you can’t have your refrigerator serviced by professionals, then here is how you can clean your condenser fan yourself. But again, WE HIGHLY DISCOURAGE this.

  1. Turn off your fridge and unplug it from the power source.
  2. Use a screwdriver to remove the rear access panel of the refrigerator compressor. This is located in the back of the fridge.
  3. Check for any debris or loose material which could be causing the noise.
  4. Run a vacuum cleaner over the fan blades and condenser coils. If you have a hand vacuum, that’s way better since it’s less powerful.
  5. Check for any damage to the fan motor. Check if the fan blade spins properly and doesn’t scratch anything. If it has to be replaced, there are many cheap condenser fans online.
  6. If everything is in order, wipe down the area with a microfiber cloth. This can help to make sure the fan is clean and free from any loose material.
  7. Reattach the access panel, and turn the fridge back on.

This is the main solution to stopping any humming noise coming from your refrigerator. This would make a SIGNIFICANT difference.

Safety Reminders

Just make sure that you don’t damage the coils and other parts of the compressor while doing this. That would be TRAGIC.

  • While you’re there, you also want to check for any signs of damage, including the rubber grommet and evaporator fan motor grommet in the refrigerator compressor.
  • If anything needs repair or a service, it’s best to have it done by professionals. The only thing you can really try to do on your own is clean the condenser fan and surrounding parts.
  • If the evaporator fan needs replacing, it’s fairly easy to find cheap replacements for it online. There are also rubber grommets present here.
  • If the condenser, or even the whole compressor, is worn out, you may want to get a new fridge. Condensers cost A LOT, and it doesn’t make economic sense to replace just that part.

After all, a refrigerator is an appliance, and an appliance doesn’t last forever. Refrigerators have to be replaced after some time. You can’t just keep replacing parts forever.

Tip #3 Soundproof the Wall Around the Refrigerator

Now sound proofing your fridge may seem like a good idea, but we’re here to tell you that it’s a TERRIBLE IDEA. This can cause the fridge to overheat if you do it wrong.

Instead, you would want to soundproof the walls surrounding the refrigerator.

There are many ways to do this, but here is a cheap and effective way to do so.

  • You can use MDF or wood and place it on the walls surrounding your fridge. This means the back of the fridge, and if possible, the sides.
  • Attach mass loaded vinyl to it with nails.
  • Cover it with acoustic foam panels. You can attach this with glue.

And VOILA! The area around your fridge is successfully soundproofed!

This is useful, especially if you want to keep sound waves from your fridge from going to different rooms.

Just make sure your fridge is close enough to the walls to be effective, but not touching or too close, to avoid overheating. So make sure not to block the air vents of the refrigerator, or you will have to service it!

If you can only invest in one thing for soundproofing, get the acoustic foam panels. These help to absorb sound, and in this case, it’s more useful than deflecting sound.

Tip #4 Enclose Your Fridge

Putting your fridge in an alcove would be a GREAT IDEA.

Not only would it look cool, but it would also help to enclose the sounds of the fridge to one small area. Not to mention, you can soundproof the alcove.

If you don’t have an alcove in your home, don’t fret. You can build shelving around your fridge to enclose it.

This has the same effect. It even LOOKS BETTER when your fridge isn’t alone. Talk about stylish and functional!

Tip #5 Fill Your Fridge

An empty fridge is definitely NOISIER than a full fridge.

This is because an empty fridge will keep turning off to conserve power.

When a fridge is full, it will run consistently to keep all the food inside cool!

So filling your fridge can definitely help with this problem! Not only will this keep your fridge quieter, but it will also make sure you never go hungry!

If you can’t fill your fridge for any reason, then fill it with bottles that are filled with water. This will trick your fridge into thinking that there’s food inside.

Tip #6 Move Your Fridge

If the overall noise from your fridge is bothering you in a particular location, then you can just move it to a place where it won’t bother you.

For example, if your fridge is in your bedroom or study area, you might want to just keep it in the kitchen where the excess noise won’t bother you.

This will significantly solve your problem in this case.

Tip #7 Use White Noise

If all else fails, distracting yourself from the fridge noise will help. This is great if you don’t necessarily need a quiet fridge. You just don’t particularly LIKE the noise.

You can get a white noise machine for this, or play music on a speaker. Both can give positive effects for your mood, too!

This is a great TEMPORARY solution to a bigger problem. You will eventually want to invest in a better and quieter fridge or fix your fridge if needed.

Most of the time, if none of the other tips works, it is time to invest in a new fridge for your kitchen.

Are Refrigerator Noises Dangerous?

The answer to this depends on a few things. Some noise problems need to be addressed, while some really aren’t problems at all.

Firstly, you need to pinpoint which part of the fridge the noise is coming from. It could come from:

  • The ice maker
  • Compressor
  • Drip pan
  • Other parts of the fridge

Possible solutions include:

  • If the noise is coming from the compressor, then you may want to have it serviced.
  • If the noise is coming from the ice maker, then most likely, it is just ice being made.
  • If it’s coming from the freezer, then you may want to have the evaporator fan replaced.

Next, take note of how loud the sound is. A refrigerator always makes low buzzing noises. But if it’s making an unsettlingly loud noise, then you might want to have it checked.

So is a buzzing fridge dangerous? In most cases, no. Refrigerators will make low buzzing and humming noises to function.

You just want to make sure you have regular maintenance on your fridge to keep it from breaking down. In general, it is very not likely to explode. So you’re safe.

If the vibration noise is signifying potential problems, it will normally come with other telltale signs. In this case, you can choose to fix or repair it, or if it’s an old refrigerator, it may be more worth it to buy a new one.

Most of the time, you should be more concerned if your fridge is silent!

Final Thoughts

Now that you know how to stop that annoying buzzing coming from your refrigerator, it’s time to do it and enjoy the silence!

One thing we did not include was soundproofing the inside of the fridge.

This is because this can cause MORE HARM than good.

It isn’t hygienic, as putting rubber mats or acoustic foam inside could contaminate the food. It can also cause the fridge to overheat, which would eventually break your fridge.

So if you were considering doing this, we highly advise against it.

The sounds coming from your fridge may be annoying, but trust us, a broken fridge is EVEN MORE annoying!

The options given should be more than enough to silence your fridge. Hopefully, these tips on how to stop refrigerator from buzzing helped you to eliminate that annoying buzzing noise!
