How Do I Know If My Dyson Hair Dryer Motor Has Gone Bad?

Regarding high-end haircare tools, the Dyson hair dryer stands at the top of the innovative design and powerful performance in any hair dryer in the market. 

However, like any device, it can encounter problems, particularly with its motor, which is the heart of the dryer. Identifying when the motor of your Dyson hair dryer has gone wrong is crucial for maintaining its functionality and ensuring optimal performance.

First, consider the power issues. If your dryer struggles to start or shuts down unexpectedly, this could indicate a motor problem. Also, pay attention to unusual noises. A healthy motor runs smoothly, so it’s a red flag if you hear grinding, rattling, or high-pitched sounds.

Another sign is ineffective drying. A compromised motor may reduce airflow, making achieving the desired drying effect difficult. Additionally, the dryer might overheat, leading to safety concerns and potential damage.

Understanding these signs can save you from inconvenience and unexpected expenses. In this blog, we’ll guide you through the indicators that suggest your Dyson hair dryer’s motor may need a check or replacement.

Conducting routine maintenance and addressing any issues promptly will ensure your Dyson dryer continues to deliver top-notch performance.

Initial Symptoms of Dyson Hair Dryer Motor Failure

When your Dyson hair dryer begins to malfunction, it might be challenging to pinpoint the problem immediately. However, specific early symptoms can indicate that the motor might be failing.

Being aware of these signs can help you take timely action to fix or replace the motor, potentially saving you from the inconvenience and cost of a complete dryer replacement.

Unresponsive or Intermittent Power

One of the most straightforward indicators of a problem with your Dyson hair dryer’s motor is issues with power responsiveness.

If your hair dryer fails to turn on consistently or at intervals during which it won’t operate, the motor could be at fault. Intermittent power might sometimes be mistaken for a faulty switch or a loose connection, but if these have been ruled out, the motor should be considered as the possible culprit.

This symptom can manifest as a complete lack of response from the device or a tendency to shut off unexpectedly during use.

Unusual Noises and Smells

A healthy Dyson hair dryer operates quietly and without burning or unusual smells. If the motor fails, you may hear grinding, buzzing, or whirring noises that weren’t present before.

Such sounds could suggest that the motor’s internal components are wearing out. Additionally, the smell of burning plastic or electronics indicates that the engine is overheating or malfunctioning. These sensory warnings are often the most noticeable signs that prompt users to check their devices.

Diagnostic Steps to Confirm Motor Issues

Before you decide to replace your Dyson hair dryer’s motor, it’s essential to conduct a thorough check to confirm that the motor is the issue. Here are some steps you can follow to diagnose motor problems accurately.

Checking Indicator Lights and Error Messages

Your Dyson hair dryer has indicator lights to provide insights into what might be going wrong. For example, flashing lights can sometimes indicate a need to clean the filter, which is a more straightforward fix.

However, if the filter is clean and the lights flash or display other unusual patterns, this could point to a more severe issue like motor failure. It is highly advisable to consistently consult your user manual to gain understanding what different light indications mean in the context of your specific Dyson model.

Manual Inspection and Filter Cleaning

Physically inspecting your hair dryer can reveal obstructions or dirt that might be causing the motor to overheat or function poorly.

Follow the steps to properly clean the filter, as your Dyson’s user manual outlines. This often involves removing the filter, rinsing it under water, and checking for debris that might obstruct airflow. A clean filter ensures optimal performance and can sometimes resolve what initially appears to be a motor issue.

Technical Troubleshooting and Disassembly

If basic cleaning and resetting do not solve this issue, it may highly be necessary to delve deeper into the hardware. Disassembling your Dyson hair dryer involves removing screws and carefully separating parts according to the guidelines provided by Dyson or available from reliable sources online, like instructional repair videos or walkthroughs.

Once you access the motor, look for wear, burning, or corrosion signs. It’s also an excellent chance to test connections with a multimeter to ensure the motor receives power. Always ensure the hair dryer is unplugged before attempting any disassembly.

Handling complex internal components can be challenging and require professional assistance. Should you require clarification on any particular step or the diagnosis reveals that the motor is faulty, consulting with a professional repair service or contacting Dyson support for advice is recommended. Ensuring proper handling can prevent further damage and help maintain your device’s warranty conditions.

Common Issues Based on Researched User Experiences

Warranty and Lifespan Concerns

Many users have expressed concerns regarding Dyson Supersonic hair dryers’ lifespan and warranty coverage. From online user testimonials, including on the Dyson Community Forums, several individuals reported that their Supersonic units ceased functioning shortly after the expired warranty period.

A frequently cited issue is the motor dying, which occurs around 2.5 to 3 years of use, despite the company suggesting a lifespan of about five years for these hair dryers.

This discrepancy in expected versus actual lifespan has led to considerable frustration among customers, especially given the high cost of Dyson products. Dyson often offers a 20% discount on a replacement when these issues arise post-warranty.

However, users have noted that such discounts are routine during promotional periods and argue that better compensation should be offered for such premature failures.

Customer Service and Repair Options

Dyson provides several avenues for customer service, including a detailed troubleshooting section on their official website, support through live chat, email, and a dedicated phone line.

Despite these resources, users have encountered mixed experiences when seeking repairs or solutions for faulty Supersonic hair dryers.

Dyson’s repair policies can be restrictive for more complex issues, particularly those involving the internal motor. According to user experiences shared in the Dyson Community, repair centers may not be permitted to open and directly repair the motors of these devices.

Customers are generally encouraged to contact Dyson’s customer support for unresolved issues. Response times can vary; some customers have reported long wait times or less than satisfactory resolutions.

In cases of faulty parts, customers are directed towards purchasing replacement parts such as filters or external accessories directly from Dyson’s website or approved retailers.

However, when the problems involve internal components like the motor, users often find themselves with limited repair options, leading to added expense in purchasing a new unit, sometimes at a marginally discounted rate.

Overall, while Dyson offers multiple support channels and seems to effectively address some surface-level issues, deeper mechanical problems, particularly post-warranty, often leave customers seeking more substantial support or facing the prospect of replacing their expensive hair dryers sooner than expected.


By understanding the signs and troubleshooting methods, you can more effectively identify when your Dyson Supersonic hair dryer might have a motor issue. From blinking lights to changes in noise and airflow, these indicators are critical for proactive maintenance.

If your DIY fixes don’t solve the problem, or if your dryer shows continuous symptoms as listed above, it might be time to contact Dyson for professional advice or service.

Regular maintenance like filter cleaning and ensuring proper handling can extend the life of your Dyson hair dryer, providing value and adequate performance for a more extended period.

Remember, if the motor is truly at fault and repair seems unfeasible, investing in a replacement might be your best option to ensure continued high performance and hair care satisfaction.
