Dyson Hair Dryer Overheating? – (Instant Fix Guide!)

Dyson hair dryer overheating can be a concerning issue, as when it occurs, you could suspect that there is hardware damage to your device.

However, in many cases, overheating can be resolved with minor troubleshooting and proper device maintenance. 

To keep your Dyson’s hair dryer from constantly overheating, start by checking for obstructions in airflow and removing any attachments.  Next, clean the air filter.

Now you have a clearer overview of some troubleshooting steps we will attempt. Let’s not see the underlying causes of a Dyson hair dryer overheating. 

Why is My Dyson Hair Dryer Overheating?

Dyson Hair drivers come in different models and types, but universally, all of them are prone to overheating when air struggles to pass through the device.

This can occur due to foreign objects blocking the airflow or incorrect configuration.

Here are some of the most notable causes for hair dryers like the Dyson to overheat:

Now that you have the general overview of the common causes for Dyson hair dryers overheating let’s test out some actionable solutions to try and fix it.

How to Fix Dyson Hair Dryer Overheating

Tip: Experiment using the cool air button more frequently and keeping the dryer at a longer distance.

Solution #1: Check Attachments and Ensure no Airflow Restrictions

Whenever your Dyson hair dryer keeps overheating, the first thing to check is if your attachments or foreign objects restrict the airflow.

As air has smaller gaps to go through, the fan motor will struggle to take in cool air, resulting in overheating.

Here are some general tips on how to ensure no obstructions for your Dyson device:

1. Turn off and unplug the Dyson hair dryer and inspect the air outlet for any obstructions or blockages.
2. Use a thin tool or a can of compressed air to clear any debris from the air outlet (the mesh on the back of your Dyson).
3. Before turning your Dyson back on, remove any attachments, as they can cause it to reach higher temperatures if improperly installed.
4. Check the vent on the back of the Dyson hair dryer for blockages and clear them.
5. Plug the hair dryer back in and turn it on to check if the airflow is restored.

If you notice that your attachments, such as hair brushes, are obstructed with hair, clean them beforehand, as this can restrict airflow and cause overheating.

Note: Check if your Dyson attachments, such as combs or diffusers, can rotate freely without any issues.

Solution #2: Inspect for Internal Issues

An often overlooked Dyson hair dryer overheating fix is to check if there are any lodged particles or debris inside the device or if the internal components are damaged.

Both of these scenarios are causes for overheating, as any loose component might obstruct your Dyson airflow.

Here are some ways to check if your Dyson hair dryer has faulty internal components:

1. Always start with the Dyson dryer unplugged before handling it – ensure it sits for a few minutes to cool down.
2. Look for signs of heat-related damage, such as a burnt smell or darkened plastic areas around the Dyson body.
3. Gently shake the hair dryer from side to side to identify if there are any loose internal components. 
4. Check if the power cord has creases where it attaches to the base of your Dyson dryer.
5. Note down if other issues accompany the overheating – such as a lack of lights blinking or buttons not working. 

If you discover any of the above issues present, it’s best to send your device for repair to a licensed shop.

Note: Ensure that opening your Dyson device for inspection won't void your warranty.

Solution #3: Monitor the Time and Heat Intensity 

Dyson hair dryers, like any other hair dryer, can overheat if used at their highest intensity for prolonged periods of time.

Most Dyson models are equipped with LED indicators that change color to give you a notice of how hot the device is running.

Here are the ways to ensure you are correctly using your Dyson device to keep it cool:

• Be mindful of the duration you continuously use the Dyson hair dryer – this can vary depending on other factors such as ambient room temperature and humidity.
• Note the 3 LED lights indicating how hot your Dyson is currently running. When you reach two or three glowing lights, please turn off your Dyson or let it cool down before further use.
• When using the device, press the ‘Cold Shot‘ button in blue for approximately 10 seconds while drying your hair to ensure optimal temperature and avoid overheating.
• Allow the hair dryer to cool down between extended use sessions.
• Avoid using the hair dryer on its highest heat setting for longer than a minute.

Note: You could use a timer to remind yourself to turn off the device after the recommended usage period.

Solution #4: Examine the Power Source and Cord

Another source that can possibly negatively affect your Dyson device is a faulty power source or power delivery system.

This is because an unstable current can cause the internal motor to work overtime and overheat rapidly.

Here is how to ensure your Dyson hair dryer has the correct power configuration:

1. Unplug the Dyson hair dryer and inspect the power cord for any visible damage.
2. Ensure the power outlet functions correctly by testing it with another device you know works beforehand.
3. If the power cord is damaged, replace it with a new one if you possess the tools and knowledge; otherwise, send it to a professional repair.
4. Try using a different power outlet to rule out issues with the initial socket – be careful when handling the Dyson in a wet or humid environment, especially after a shower.
5. Ensure the power supply matches Dyson’s recommended voltage and frequency – North America uses the standard 120V outputs.

Note: If you use the Dyson on a power strip, ensure that the other devices are not overloading your Dyson.

Solution #5: Check the Dyson Filter

Most Dyson models come with a removable filter that is meant to be serviced every once in a while, depending on use.

If this Dsyons air filter becomes blocked, it will cause your hair dryer to overheat very quickly, even after just a few minutes of use.

Here are the general steps to clean and maintain your Dyson air filter:

1. Ensure your Dyson hair dryer is unplugged and cool before starting.
2. Locate the filter, typically at the bottom of the dryer, and twist it to remove it.
3. Clean the filter with the help of a soft brush and then rinse it under warm, soapy water for a few minutes.
4. When you are done washing your Dyson filter, allow it to dry completely before reinserting it into the Dyson hair dryer.
5. Double-check that the filter is securely in place before plugging the device back in – it has to be rotated and “clicked” in position.
6. After cleaning the filter, look down into the hair dryer base to see if there is lodged debris inside, and clean them with pressurized air if needed.

Note: The entire area around the Dyson handle can usually be serviced by cleaning it via a brush or a can of high-pressure air.

Solution #6: Ensure Proper Environment 

Sometimes, your Dyson hair dryer is working as intended. However, an external cause is making it overheat.

This can happen if the place you are using your Dyson helps raise its internal temperatures – meaning you have to adapt your usage patterns to cool it down.

Here are some tips to ensure your Dyson hair dryer is not overheating:

1. When cleaning the air intake mesh of your Dyson, never use cotton swabs, as they can leave behind strains that can ignite or burn during use.
2. Assess the ambient temperature in the room where you are using the Dyson hair dryer.
3. Avoid using the hair dryer in excessively hot or humid conditions, as it may strain the internal components.
4. Ensure proper ventilation in the room to dissipate heat generated during operation – if used in a bathroom after a hot shower, it’s best to ventilate the room first.
5. Avoid using the Dyson in open areas with high air temperature – such as on a beach.
6. Lower heat settings suit thin or delicate hair, so adjust your Dyson accordingly.

Note: Always apply a heat protectant spray before using the hair dryer to protect your hair from heat damage.

Quick Recap

To fix the Dyson hair dryer overheating, start by ensuring the air filters are not obstructed or clogged.

Next, consider the environment temperature and use the cool air button more often.
