Refrigerators can be the cause of all types of racket in your kitchen, day and night. From moaning and rattling to whistling, your fridge may have you convinced you live in a haunted house instead of simply the refrigerator making noise. But have no fear, when you start to hear a refrigerator high pitch noise that reminds you of a whistling sound, it usually stems from one of very few places. If you know where to look in the refrigerator, you can probably identify the source of the noise quickly and make any necessary repairs.


Fan in the Freezer

If you notice a refrigerator high pitched whining sound or whistling noise in your appliance coming from the vicinity of the freezer compartment, the most common reason for it will be the evaporator fan. Like any electric fan, it's powered by a motor.

The fan might make a variety of noises that include squealing, chirping, whistling and even moaning. This is usually because the lubrication is gone or the bearings are worn out. You'll need to have the evaporator fan replaced entirely since the fan motor cannot be lubricated.

Forced Air Fan

The evaporator fan can cause a mild whistling sound while working normally. This fan draws air over the cooling coils and forces air to circulate throughout the refrigerator. The forced air moves through the various orifices in the freezer and fresh food compartments.


In some models this air causes a whistling sound as it passes through the openings throughout the refrigerator. This is a normal noise and nothing to be concerned about.

High-efficiency Compressor Noises

Newer refrigerators are likely equipped with high-efficiency compressors, which run much faster than older compressors. They get the job done more quickly with less energy, but can also make a different noise than old compressors.


These high-efficiency units may produce a high-pitched whine or hum. Some consider this whining sound to be a whistle. Unfortunately, if this noise is bothersome, you'll have to live with it as long as you have the refrigerator, as it's the normal operating sound of your particular refrigerator.

Fan in Rear of Refrigerator

If the whistling sound in your refrigerator is coming from the rear of the unit, the condenser fan may be the culprit. The condenser fan motor can squeal or whistle if the motor bearings are worn out, which requires replacing the fan motor. If the fan has gotten dirty from dust or lint, it could also be affecting the movement of the fan and cause different sounds such as whistling or humming.


Fixing Refrigerator High Pitch Noise

Because the sources of refrigerator whistling noises are from electrical components, you may want to call in a refrigerator repair specialist unless you're skilled in these types of electrical repairs. If you do decide to tackle this DIY project, be sure to unplug the refrigerator before you start working so that you won't experience an electric shock. And be sure to replace the faulty part with a factory-approved replacement designed for your particular model.
