Strange Sounds and the Health of Your Fridge
We rely on our refrigerators every day to keep our food fresh and our routines in order. However, when unexpected noises start coming from inside or behind the unit, it often signals that something isn’t working properly. That is to say, your refrigerator may be alerting you to a developing issue that needs attention.
Above all, identifying these noises early can help us avoid larger, more expensive problems down the line. For example, a consistent buzzing could mean a faulty compressor, while clicking might point to an issue with the start relay. In addition, some noises are just normal operational sounds, so knowing the difference is essential for peace of mind and performance.
Clicking Sounds Coming From Behind the Unit
Clicking is one of the most common refrigerator noises homeowners notice. Therefore, when we hear rapid or irregular clicking from behind the fridge, it typically means the compressor is trying to start but cannot. In other words, the start relay might be failing to power up the motor.
On the other hand, if the clicking is followed by complete silence, it could indicate your refrigerator isn’t cooling properly anymore. Consequently, this affects the preservation of your groceries. If this happens repeatedly, we recommend you explore fridge repair services in Calgary to inspect the internal components before the situation worsens.
Humming and Buzzing That Won’t Stop
We expect some humming from our refrigerators, especially when the compressor or fans are running. However, if the humming becomes noticeably louder or more frequent, we might be dealing with a worn-out motor. To clarify, when the motor has to work harder than usual, it can create excessive noise as it pushes air through dirty coils or blocked vents.
Most importantly, a buzzing sound can also come from the ice maker, particularly if the water line is not connected. As a result, it’s crucial to determine where the noise originates. If unsure, our team always suggests getting professional advice to avoid causing further damage through trial and error.
Rattling and Vibrating Noises
Rattling usually points to something minor but still important to resolve quickly. For instance, if the fridge isn’t level or has items placed loosely on top, vibrations can cause parts or objects to shake. Similarly, compressor vibrations can transfer through the floor or walls, increasing the noise level.
That is to say, minor positioning adjustments often silence these sounds. However, if the rattling comes from within the unit or continues despite adjustments, it could involve the condenser fan or internal tubing. In this case, we often recommend that customers request a professional appliance inspection to evaluate the source without risking damage.
Whirring and Fan-Related Issues
When we hear a whirring or whooshing sound, it typically relates to one of the refrigerator’s fans. These fans help regulate airflow throughout the system. However, when blocked or beginning to wear out, they may produce irregular or sharp whirring sounds that fluctuate in intensity.

Sizzling, Popping, or Cracking Sounds
While sizzling or cracking can be alarming, they often aren’t as serious as they seem. For instance, these sounds commonly happen during the automatic defrost cycle when ice melts from the coils and drips onto the heating element. Similarly, cracking can occur when plastic components inside the unit expand and contract with temperature changes.
But if the noises persist outside of these normal patterns, it may indicate a wiring issue or loose electrical connection. Above all, if you smell anything unusual—like burning plastic—while hearing these sounds, unplug the unit and seek professional help immediately. Safety should always come first, especially when electricity is involved.
Gurgling and Water-Related Sounds
Sometimes, you might hear gurgling or bubbling noises as your fridge runs. These are usually signs that refrigerant is circulating through the coils. In the same vein, water dripping or trickling could mean the defrost drain is working as expected. Therefore, these sounds alone may not require service unless they are excessive or continuous.
However, if water begins to pool at the bottom or leak onto the floor, there may be a blockage in the drain tube or a cracked tray. Consequently, these problems can lead to mold, odors, or even electrical shorting. We always advise checking the back of the fridge for water buildup as part of your monthly maintenance routine.
When to Call for Professional Help
We’ve outlined many possible causes for common refrigerator noises. However, not every homeowner feels comfortable diagnosing or repairing appliance issues. In conclusion, strange sounds that increase in volume, frequency, or severity are usually your fridge’s way of telling you something is wrong.
Certainly, professional diagnosis can prevent bigger issues from forming. Moreover, waiting too long can lead to more expensive repairs or even full replacement.
