What Causes Noise from Your Refrigerator?

A noisy refrigerator can be disruptive and annoying. But what exactly causes a fridge to hum, rattle or vibrate? Here are some of the most common culprits of refrigerator noise and how to address them.

The Compressor

The compressor is the main source of noise in most refrigerators. It pressurizes refrigerant to enable cooling. Old, worn or damaged compressors are prone to making loud hums or rumbles when running. Replacing an outdated compressor is often the best solution for minimizing noise.

The Condenser Fan

The condenser fan removes heat from the refrigerator coils. If the fan blade is warped, rubbing, or unbalanced, it can create buzzing, clicking or rattling sounds. Check for debris stuck in the fan housing. Cleaning or replacing a faulty fan usually quiets it down.

Loose Internal Components

Parts inside the fridge cabinet like shelves, drawers or trays can vibrate and rattle if not properly secured. Make sure all screws and fasteners are tightened. Adjust any parts rubbing against the walls. Adding felt tape helps muffle vibrations.

Defrost Control Board

Modern refrigerators have a control board that runs the defrost cycle. If this circuit board is faulty, it can cause strange humming or pulsing noises during defrosting. Replacing the defrost control board typically solves this.

Iced Up Evaporator Coils

Ice buildup on the evaporator coils blocks airflow, making the fridge work harder. This strains the compressor and leads to humming. Defrosting the ice or improving door seals to prevent frost resolves this issue.

Low Refrigerant Charge

Not having enough refrigerant makes the compressor run harder to try to cool, causing strain and noise. A technician can check the refrigerant level and recharge the system if low. Refrigerant leaks may also need to be repaired.

Loose Parts

Check for any loose compressor mounts, tubing or external components. Tighten up any brackets securing the condenser coil and compressor. Installing vibration-absorbing pads under the compressor can reduce noise from external vibrations.

How To Make Fridge Quieter: 8 practical tips

Is your refrigerator making rattling or humming noises that are disrupting your home environment? A noisy refrigerator compressor or condenser fan can be annoying and distracting. Luckily, there are several DIY methods you can try to quiet a noisy fridge before you need to call in an appliance repair professional.

Determining the Source of the Noise

The first step in silencing a loud refrigerator is to identify the source of the noise. Open the refrigerator door and listen closely to pinpoint where the sound is coming from.

  • A rattling noise could indicate a loose part that needs to be tightened.
  • A humming or buzzing noise likely means the condenser fan is out of balance or dirty.
  • A hissing or gurgling sound points to an issue with the refrigerant flow.
  • Knocking or thumping is usually the compressor malfunctioning.

Finding the origin of the noise will direct you to the proper solution.

Check for Loose Parts

If you hear rattling, check the refrigerator thoroughly for any loose screws, brackets, shelves or door bins. Tighten them securely to stop vibrations that cause rattling. Examine the compressor and condenser fan for loose fasteners or mountings. Tighten them if needed to prevent humming and buzzing.

Clean the Condenser Coils

Dirty condenser coils can cause the refrigerator compressor to strain excessively to remove heat. This leads to louder running and rumbling. Regularly clean the condenser coils located at the back of your refrigerator with a vacuum hose or duster. Make sure air can circulate freely around and through them.

Ensure Proper Leveling

An unleveled refrigerator rocks and vibrates, creating unnecessary noises. Place a level on top of your refrigerator. If needed, adjust the levelling legs underneath until the refrigerator is perfectly levelled horizontally. This stabilizes it and reduces rattling vibrations.

Use Vibration Pads

Vibration-absorbing pads or feet prevent excess motion that leads to noise. Place thick rubber pads under each refrigerator leg to dampen vibrations and reduce rattling and humming noises. Self-adhesive felt furniture pads also work well.

Add Soundproofing Materials

Lining the inside of your refrigerator compartment with adhesive soundproofing materials like mass-loaded vinyl (MLV) can mute the compressor and fan noise. MLV vinyl is dense and excellent for blocking noise. Just like the interior refrigerator surfaces with the vinyl sheets.

Acoustic foam panels on the exterior refrigerator walls can also mute vibrations and sounds. The panels absorb sound rather than blocking it completely. Place panels on any outside surface that emits noise.

Replace Defective Parts

With age, refrigerator parts like fan blades and compressors wear out and become noisier. Replacing defective parts with new ones will permanently solve noise issues. Consider installing higher-quality replacement parts designed for quiet operation.

Call An Appliance Repair Technician

For persistent noise that you cannot resolve, contact an experienced appliance repair technician. They have the skills and expertise to diagnose and fix any refrigerator noise issues. A technician can replace worn parts or realign components.

A noisy refrigerator compressor or condenser fan can be very disruptive. Identifying and addressing the source of the noise using one of these methods will restore peace and quiet to your kitchen. With some diligent troubleshooting and DIY repairs, you can easily make your noisy refrigerator quiet again.

How to Prevent Refrigerator Noise from Happening Again

Once you’ve successfully quieted a noisy refrigerator, you’ll want to take steps to prevent the sounds from coming back. With some simple maintenance and care, you can stop annoying hums, rattles and vibrations before they start.

Regularly Clean the Condenser Coils

Dust buildup on the condenser coils can force the refrigerator to work harder and louder. Every 3-4 months, vacuum the coils located on the back and bottom of your fridge. Keeping them free of debris improves airflow and efficiency.

The condenser fan should also be cleaned regularly. Use a small brush or compressed air to remove any dust or dirt from the fan blades and housing. A clean condenser system prevents strain on the compressor.

Check the Leveling

An unleveled refrigerator can cause vibrations that lead to humming or rattling. Every few months, confirm your fridge is evenly levelled using a bubble-level tool. Adjust the levelling feet underneath as needed to keep it balanced.

Don’t place the refrigerator on an uneven floor. Any sagging spots or inconsistencies in the flooring can throw off the fridge’s balance. Choose a solid, flat area of your kitchen.

Avoid Overloading the Refrigerator

Putting too much food or overly heavy items in the refrigerator stresses the compressor. Only fill shelves to about two-thirds capacity and avoid overloading door bins.

Let hot food cool down before placing it inside. Adding a lot of warm items forces the fridge to run harder to keep temperatures even, causing strain and noise. Leave enough space for air to properly circulate.

Keep It Away from Heat Sources

Position the refrigerator away from any heat sources such as ovens, dishwashers or heating vents. Exposure to excess heat taxes the compressor and condenser. Even a few inches of separation can make a difference.

Maintain proper ventilation space around the entire fridge. Don’t install it in enclosed spaces with limited airflow. Give the coils enough room to release heat properly to avoid overworking the compressor.

Replace Worn Parts Promptly

Components like fan motors and compressors wear out over time. If any parts are reaching the end of their lifespan, have them replaced to head off excessive noise issues. Preventative maintenance saves you from dealing with disruptive sounds down the road.


How Much Does It Cost to Fix a Noisy Refrigerator?

The cost to fix a noisy refrigerator ranges from $200 to $600 on average. Minor issues like a rattling fan or loose parts may cost around $200 to $300. Major repairs like replacing the compressor can be $500 to $600 or more.

Can I Fix a Noisy Refrigerator Myself?

You can often resolve minor refrigerator noises yourself. Simple fixes like tightening loose screws, cleaning coils, or installing vibration pads are doable for DIYers. Follow troubleshooting tips to isolate and muffle noises.

How Often Should I Clean the Coils on My Refrigerator?

Clean the condenser coils every 3-4 months for optimal efficiency. Dust and debris accumulate quickly on coils and need regular removal. Vacuum and brush the coils quarterly to improve airflow.


Dealing with disruptive humming, buzzing or rattling from your refrigerator can be frustrating. But in most cases, you can successfully silence the noise with some simple troubleshooting and maintenance.

The key steps are identifying the sound source, checking for loose parts, cleaning the condenser coils, levelling the fridge, using vibration pads, and replacing any worn components. For excessively loud compressors or complex issues, rely on the expertise of a professional technician for fixes.

With some hands-on effort and preventative care, you can stop annoying refrigerator noises in their tracks. Pay attention to any new vibrations or sounds that develop, and address them promptly before they worsen.

Your refrigerator should operate quietly and efficiently, keeping your food chilled without disturbing your peace and quiet.
