How To Fix Dyson Fan Noises? Troubleshooting Guide

Dyson fans are known for being sleek and well-designed. But, more importantly, they’re incredibly silent, thanks to the absence of fan blades. So, an abnormal noise from a Dyson fan unit is a clear-cut sign of a problem.

Dyson fans can make problematic noises like clicking and grinding from physical obstructions and dust clogging. Besides that, a worn-out motor bearing can also cause a high-pitched whirring noise. Your Dyson fan can also produce unproblematic humming noises from the fan’s internal components working.

Keep reading to understand the noises you might hear from a Dyson fan, what they mean, and how to stop them.

How Do You Fix Dyson Fan Noises?

Dyson fans are generally silent and don’t make much noise under normal conditions. So if you hear audible noises from the unit, you should troubleshoot it immediately.

Here are the kinds of noises you can expect from a Dyson fan, their causes, and how you can fix them:

Clicking Noises

About this noise: The first kind of unusual Dyson fan noise you should be aware of is a clicking noise. 

This clicking noise typically happens when you activate the fan’s oscillation mode, which causes it to turn from side to side continuously.

What’s causing it: The clicking noise when your Dyson fan oscillates is caused by obstructions around the fan’s base.

In other words, items placed too closely around the unit’s base prevent your Dyson fan from turning around as it should. As the fan forces itself to turn around, it produces the clicking noise you’re hearing.

How to fix it: You can fix a clicking Dyson fan by removing any obstructions preventing it from oscillating. You can prevent this from happening again by keeping the fan’s base a safe distance from any other items.

Grinding Or Buzzing Noises

About this noise: Another noise you might experience is often described as a ‘grinding’ or ‘buzzing noise’. It’s a noise that results from friction as two things rub against each other continuously.

What’s causing it: These noises result from dust building up in the fan’s motor or other moving parts. The friction you hear is from those components moving against the trapped dust inside.

How to fix it: The solutions for this problem are somewhat limited, as the problem is internal to the Dyson fan.

You can try removing the dust from inside the Dyson using a vacuum. Alternatively, you can try blowing that dust away by using compressed air.

However, you’ll have no choice but to contact Dyson directly if those two solutions don’t work.

Whining Or Whistling Noises

About this noise: Whining and whistling noises are possible with a Dyson fan. You could also describe them as sounds of air being sucked through tiny gaps.

What’s causing it: As the description above suggested, whining or whistling noises are caused by air moving through small gaps that should not be there.

Those gaps are between the loop amplifier and the rest of the fan’s body. They’re there because the loop amplifier was not installed correctly.

How to fix it: You’ll have to close those gaps to stop these noises from continuing. To do that, remove the loop amplifier entirely. Then, inspect the fan unit for any dust, dirt, or anything else that prevents the loop amplifier from attaching correctly (without any air gaps).

Then, reinstall the loop amplifier correctly, checking to ensure no gaps are anywhere.

Humming Noise While Fan Is On Or Off

About this noise: Dyson fans can also produce a humming noise while you’re using them. Interestingly, the same noise can also occur when the fan is off but plugged into a power source.

What’s causing it: A humming noise that happens regardless of if the fan is on or off is caused by the thermostat inside. 

It makes that noise as it regulates the temperature of the Dyson fan. But that’s something that it does regardless of whether the fan is running or in standby mode.

How to fix it: In this case, there’s nothing wrong with the Dyson fan per se. Still, let’s suppose you’ve turned the fan off, and the noise is getting a bit too annoying for you.

In that case, you can stop the noise by unplugging the fan entirely or relocating it further from where you are. Both options ensure you won’t hear any more humming from the unit.

Low Humming While Fan Is Off

About this noise: When your Dyson fan is turned off, you might hear a low humming or high-pitched noise coming from the unit. 

These noises aren’t loud, but you’ll hear them if you’re close enough and there’s no ambient noise.

What’s causing it: These noises happen when your Dyson is turned off because of its Continuous Monitoring function. 

That function requires your Dyson fan to run at very low speeds, just enough to pull air over its sensors. When that happens, the sensors can then collect temperature and humidity data.

The fan sends all collected data directly to the mobile app on your smartphone or other devices.

How to fix it: You can choose to stop these noises by disabling the Continuous Monitoring function. To do that, access the mobile app on your device and scroll through its settings.

The option you’re looking for is ‘collect data when in standby. When you find it, disable that option.

High-Pitched Whirring Noise

About this noise: Lastly, malfunctioning Dyson fans can also make high-pitched whirring noises from their motor.

What’s causing it: High-pitched whirring noises come directly from the motor’s bearings. Those bearings allow the motor’s components to turn smoothly and quietly with as little friction as possible.

Unfortunately, defective or worn-out motor bearings will generate noise as they continue to move. Those noises are best described as the high-pitched whirring noise that you hear.

How to fix it: Unfortunately, internal components like the motor and its bearings are not accessible on Dyson fans. That means users can’t easily take apart the unit to fix it themselves.

So, if the noise doesn’t go away on its own, you’ll have to contact Dyson to see your options to resolve the issue. Depending on your situation, you might be entitled to a replacement, or you can send your fan in for repairs.

Frequently Asked Questions (FAQs)

Here are a few more details about Dyson fans that you’ll find helpful during troubleshooting:

Do Dyson Fans Oscillate? 

Yes, Dyson fans have an oscillation mode that causes the unit to turn continuously from side to side. That allows the fan to distribute air more evenly throughout the room.

Can I Leave A Dyson Fan On All The Time?

Yes, you can leave a Dyson fan running all the time. However, you should avoid doing so if no one is in the room. Running the Dyson fan unnecessarily will place excess wear on the fan and shorten its overall lifespan.

Is There An App To Control Dyson Fans?

Yes, you can control your Dyson fan through the Dyson Link app on your smart device. The app also displays any data collected from your Dyson fan, like humidity and temperature levels in your room.

Do Dyson Fans Collect Dust?

Yes, wherever there’s airflow, there will be dust. So, Dyson fans collect dust and should be cleaned regularly to maximize airflow.

How Often Should You Clean Your Dyson Fan?

You should clean your Dyson fan once a week. However, more frequent cleaning is necessary if the air quality in your area is particularly low. For example, areas with pets will have more dander in the air that will get caught in the fan’s filter. Protection Status
