Understanding Dyson Hair Dryer Heating Elements

Components of a Dyson Hair Dryer

The Dyson Supersonic hair dryer incorporates advanced technology to ensure hair is dried efficiently without extreme heat damage.

Central to its design is a microprocessor that manages the double-stack heating element by calculating real-time adjustments.

This is complemented by a glass bead thermistor, which measures the exit temperature 20 times every second, providing constant feedback to the microprocessor for optimal temperature regulation.

Functioning of the Heating Element

Dyson’s intelligent heat control is pivotal in maintaining the dryer’s performance. The device is equipped with a non-self-resetting thermal cut-out safety feature, which prevents overheating by shutting down the unit when necessary.

If the dryer cuts out, unplug it and allow it to cool down before attempting a reset. This safety mechanism ensures that the maximum operating temperature under normal conditions does not exceed 105°C, with the thermistor capable of withstanding up to 145°C during safety shutdowns.

Common Issues with Dyson Hair Dryer Heating Elements

Signs of a Broken Heating Element

  1. Noise and Airflow Issues: You may notice that your Dyson hair dryer produces a louder-than-usual noise, or the airflow should be more robust and warmer. These could be signs that the heating element is not functioning correctly.
  2. Intermittent Power: If the dryer turns off unexpectedly or has difficulty starting, this could indicate issues with the heating element or its connections.
  3. Unusual Smells: A burning or dusty smell can emanate from the dryer when the heating element malfunctions due to accumulated dust or a technical fault.
  4. Visible Issues: When inspected, physical damage or discolouration on the heating element might also suggest a problem.

Potential Causes of Heating Element Failure

  1. Blocked Air Ducts: Lint and hair can block the air ducts, restricting airflow and causing the heating element to overheat.
  2. Overheating: If the dryer does not shut off when it overheats, this could stress the heating element, leading to failure.
  3. Electrical Issues: Problems with the power supply, such as using an incorrect voltage or a malfunctioning cable that is hot to the touch, can damage the heating element.
  4. Faulty Components: A broken part or accessory that does not attach properly can also cause the heating element to malfunction.

By understanding these common issues and potential causes, you can better diagnose problems with your Dyson hair dryer’s heating elements. Performing routine maintenance, such as filter cleaning, can aid you to avoid many of these problems.
