Kenmore Refrigerator Makes Loud Noise

You can trust that your Kenmore refrigerator is going to provide you with years of service. When problems occur, such as if your refrigerator is making a loud noise, what can you do to fix it?

A Kenmore refrigerator can make loud noises due to several reasons. A malfunctioning variable-speed motor can cause a buzzing sound. A faulty adaptive defrost control board can result in a popping or clicking sound. Restricted refrigerant flow can cause a hissing or gurgling noise. These issues can disrupt the normal operation of the refrigerator and cause loud noises.

Variable Speed Motor

Your Kenmore refrigerator is likely equipped with a variable-speed motor. If it is not operating properly, it can cause a buzzing sound to occur.

This buzzing sound may be due to the fan not being properly aligned or it could be vibration that is caused by the motor.

In either case, the sound can be distracting and if the vibration gets too heavy, it could be very loud. Fortunately, this is also a problem that is not difficult to fix.

You can pull the variable speed motor out of the Kenmore refrigerator and test it with a multimeter. If it doesn’t test for continuity, you can replace it.

You can also try hooking up the motor and running it after it has been removed from the refrigerator. Be cautious when doing this, but it can give you an indication of the sound that is being created by the small device.

Variable speed motors in a Kenmore refrigerator cannot be repaired but they can be replaced.

Adaptive Defrost Control

It is important for the freezer in your Kenmore refrigerator to defrost on a regular basis. This is done automatically without the need for any attention on your part.

A number of different parts exist to make the defrost cycle operate properly. One of those is the adaptive defrost control board.

When the defrost control board is faulty, it could result in a popping or clicking sound. This sound typically happens when the control board either engages or disengages.

It is not possible to repair a control board but it can be replaced. Pull the control board from the freezer and visually inspect it for any type of damage or burnt circuitry.

After replacing a damaged control board, the operation of the defrost cycle should be smooth and quiet.

Refrigerant Flow

There are a number of different issues that can cause the refrigerant flow to be restricted. When you experience this problem, you may hear a hissing or gurgling noise as the refrigerant is trying to push through.

It is important not to work on the refrigerant system on your own. If you feel that you do have a problem with the refrigerant flow, contact a technician to resolve the issue.

Common Reasons Why a Kenmore Refrigerator Makes Noise

We count on our refrigerators to run without any problems. What can you do if your refrigerator is making a loud noise?

A loud buzzing or clicking sound can be the result of a failing compressor. Remove the compressor from the refrigerator and test it using a multimeter. The compressor can sometimes be fixed but in most cases, it must be replaced.

Here are five common reasons why your refrigerator may be making a loud noise and how to fix them.

Dirty Condenser Coils

When condenser coils become clogged with dust and debris, it makes the compressor work harder. Since the compressor is working harder, it will make noise.

Solution: Clean the coils with a vacuum cleaner or soft brush. Make this a regular part of your household cleaning to ensure that problems are kept to a minimum.

Faulty Condenser/Evaporator Fan Motor

Both the evaporator and the condenser fans could wear out over time. In either case, the typical sign of such a faulty fan motor is a loud noise. Some of these noises can include clicking, humming, grinding, rattling, and buzzing.

Solution: Both the evaporator and condenser fan motors can be replaced. Prior to replacing them, you can remove them from the refrigerator and test them with a multimeter.

If the motors don’t check for continuity, they are faulty and must be replaced.


An icemaker can generate noise due to it being jammed and frozen. As the auger tries to turn, it can create a loud clicking or banging sound.

Solution: Remove the icemaker components from the refrigerator and visually inspect them. In many cases, you will see the buildup of ice when you first start this process. Faulty or damaged parts should be replaced.

Loose Parts

There are many moving parts in a refrigerator and some that don’t move. If they are not attached properly and are loose or worn, they could begin making a vibrating and rattling sound.

Some common parts that experience this type of rattling include the ice maker, tubing, and loose pipes.

Solution: Carefully inspect the interior of the refrigerator for any loose or rattling parts. You can do so visually, by feeling for loose parts, or by trying to pinpoint the sound they are making.

After you fasten the loose parts in place, the smooth and quiet operation of the refrigerator should return.

Out Of Level

The refrigerator should be level and if it isn’t, it could produce a buzzing or rattling noise. This is due to vibrations that can occur when the unit is not leveled properly.

Solution: The solution to an unlevel refrigerator is straightforward. Most refrigerators are designed with leveling feet that can be adjusted to bring the refrigerator to the proper level.

Let us now consider some of the brand-specific reasons why refrigerators could be making loud noises.
