Dryer Burning Smell: Causes, Safety Steps, and When to Call for Help
A burning smell from your dryer is alarming — and it should be. While some causes are harmless (especially with new dryers), others can be fire hazards. This guide helps you identify the cause and take the right action.
Immediate Safety Steps
- Stop the dryer and unplug it (or turn off the breaker)
- Open the dryer door and check for any visible smoke or scorching
- Check the lint trap — a full lint trap is the most common cause
- Ventilate the room by opening windows
- Do not restart the dryer until you've identified the cause
Common Causes of Dryer Burning Smell
1. Lint Buildup (Most Common — 40% of cases)
Smell type: Hot, dusty, slightly acrid The issue: Lint has accumulated in the lint trap housing, exhaust duct, or inside the dryer cabinet. Lint is highly flammable — dryer fires cause an estimated 2,900 house fires per year in the US. Fix: Clean the lint trap thoroughly. Disconnect the exhaust duct and clean it out. Use a dryer vent cleaning brush kit ($15-$25). Clean inside the dryer cabinet if accessible.
2. Worn Drive Belt
Smell type: Burnt rubber The issue: The rubber belt that turns the drum is slipping, cracking, or rubbing against the drum. Common in dryers 5+ years old. Fix: Requires professional replacement ($150-$250 including parts and labor).
3. Failing Drum Bearings or Rollers
Smell type: Hot, metallic, friction smell The issue: Drum support bearings or rollers are worn, creating friction and heat. You'll also hear a grinding, squealing, or thumping noise. Fix: Professional replacement needed ($150-$300).
4. Heating Element Malfunction
Smell type: Burning electrical smell, acrid The issue: The heating element has shifted, broken, or is touching the drum housing. If a coil breaks and contacts metal, it creates a short that smells like burning electrical wiring. Fix: Professional replacement needed ($150-$350).
5. Thermostat or Thermal Fuse Failure
Smell type: Overheating smell, clothes feel scorching hot The issue: The thermostat that regulates dryer temperature has failed, causing the dryer to overheat. The thermal fuse may have blown. Fix: Professional replacement needed ($100-$200).
6. Foreign Objects
Smell type: Burning plastic, chemical The issue: A crayon, pen, plastic item, or lighter was left in a pocket and is melting in the heat. Fix: Stop the dryer, remove the item, clean the drum with rubbing alcohol.
7. New Dryer Break-In (Harmless)
Smell type: Mild chemical/industrial smell on first 5-10 uses The issue: Manufacturing oils and coatings burning off during initial use. This is normal. Fix: Run empty on air-dry cycle for 20 minutes. Smell should fade after 5-10 uses.
