What to Do If Your Hair Dryer Smells of Burning

Last updated: 3 August 2025

Step 1: Unplug It Immediately

If your hair dryer smells of burning, turn it off and unplug it straight away. Continuing to use it could pose a fire risk or cause damage to the internal components.

Step 2: Check for Lint or Dust Build-Up

Hair dryers often suck in dust, lint, and hair through the rear air intake. This build-up can overheat and emit a burning smell. Remove the back cover or filter if your model allows, and gently clean it using a small brush or vacuum.

Step 3: Inspect the Cord and Plug

Examine the power cord and plug for any signs of melting, fraying, or scorch marks. These could indicate a serious electrical fault. If damaged, the dryer should not be used again.

Step 4: Smell Inside the Barrel

Once it's cooled, smell near the front of the dryer. A strong burnt smell may suggest internal components (like the motor or heating element) are overheating or failing — a sign that the device may be unsafe to use.

Step 5: Test on a Safe Surface (Optional)

If you cleaned the dryer and found no visible damage, you can test it on a heatproof surface for a few seconds while supervised. If the smell persists, stop using it.

Step 6: Consider Repair or Replacement

Inexpensive hair dryers often aren’t worth repairing. If it's under warranty, contact the manufacturer. Otherwise, replacing it is typically safer and more cost-effective.

Extra Safety Tips

  • Avoid using hair dryers near water or in damp conditions
  • Let the dryer cool fully before storing it
  • Don’t cover the air vents during use
  • Clean the air intake regularly to prevent build-up
