Why Is My Fridge Humming? Tips to Stop Loud Humming Noises

Why Is My Refrigerator Humming?

Refrigerators are an essential appliance in any household, keeping our food fresh and our beverages cold. However, it can be quite concerning when you start to hear a loud humming noise coming from your refrigerator. In this article, we will explore the reasons behind this humming sound and provide troubleshooting examples and solutions to help you address the issue.

Why Is My Refrigerator Making a Loud Humming Noise?

If your refrigerator is making a loud humming noise, there could be several reasons behind it. Let’s take a look at some of the common causes:

  • Compressor: The compressor is an integral part of the refrigerator that helps circulate the refrigerant and maintain the desired temperature. However, over time, the compressor can become worn out or faulty, leading to a loud humming noise.
  • Fan Motor: Refrigerators have both condenser and evaporator fans that help circulate air throughout the unit. If the fan motor is malfunctioning or has accumulated debris, it can produce a humming sound.
  • Condenser Coils: The condenser coils are responsible for releasing heat from the refrigerator. If these coils are dirty or clogged, it can cause the compressor to work harder, resulting in a humming noise.
  • Water Valve: Some refrigerators come with a water dispenser or ice maker, which requires a water valve to operate. If the water valve is faulty or not properly connected, it can create a humming sound.

Why Is My Fridge Humming?

Similar to refrigerators, fridges can also produce a humming noise due to various reasons. Let’s explore some of the common causes:

  • Temperature Control: The temperature control mechanism in a fridge can sometimes cause a humming noise, especially if it is set at a high cooling level. Adjusting the temperature control to a lower setting may help reduce the humming sound.
  • Defrost Timer: Fridge models with automatic defrosting features have a defrost timer that can produce a humming noise during its operation. This is a normal occurrence and not a cause for concern.
  • Condenser Fan: The condenser fan in a fridge helps dissipate heat from the unit. If the fan motor is faulty or obstructed, it can lead to a humming noise.

Why Is My New Fridge Making a Loud Humming Noise?

If you have recently purchased a new fridge and it is making a loud humming noise, it can be quite frustrating. Here are a few possible reasons for this issue:

  • Installation: Improper installation of the fridge can cause vibrations and result in a humming noise. Ensure that the fridge is level and all components are securely in place.
  • Transportation Damage: During transportation, the fridge may have experienced jolts or impacts that could have damaged internal components. Contact the manufacturer or retailer for assistance if you suspect transportation damage.
  • Manufacturing Defect: In rare cases, a manufacturing defect can cause a new fridge to produce a loud humming noise. If this is the case, it is advisable to contact the manufacturer for a replacement or repair.

How to Stop Refrigerator from Buzzing

Now that we have explored the possible causes of a humming noise in refrigerators and fridges, let’s discuss some troubleshooting steps to help you address the issue:

  • Clean the Condenser Coils: Regularly cleaning the condenser coils at the back or underneath the refrigerator can improve its efficiency and reduce the workload on the compressor, potentially eliminating the humming noise.
  • Check the Fan Motor: Inspect the fan motor for any obstructions or signs of damage. If necessary, clean the fan blades and ensure that the motor is functioning properly.
  • Adjust the Temperature Control: If the temperature control is set too high, it can cause the compressor to work harder and produce a humming noise. Try lowering the temperature setting and monitor if the noise reduces.
  • Call Authorized Service: If the humming noise persists or you are unsure about performing any troubleshooting steps, it is recommended to call the authorized service center for assistance. They have the expertise to diagnose and resolve complex issues.

Replacement Parts for “Why Is My Refrigerator Humming”

If you have identified a faulty component in your refrigerator or fridge that is causing the humming noise, you may need to replace it. Here are some common replacement parts you might require:

  • Compressor: The compressor is a crucial component, and if it is faulty, it may need to be replaced. Contact the manufacturer or an authorized service center to obtain the correct replacement compressor.
  • Fan Motor: If the fan motor is causing the humming noise, you can purchase a replacement fan motor from appliance parts stores or directly from the manufacturer.
  • Water Valve: For refrigerators with water dispensers or ice makers, a faulty water valve can be the culprit. Replacement water valves can be obtained from appliance parts suppliers.


Hearing a loud humming noise from your refrigerator or fridge can be concerning, but it is often a solvable issue. By understanding the possible causes and following the troubleshooting steps mentioned in this article, you can address the problem and restore your appliance to its normal functioning.
