• Smell resembles burning hair or plastic
• Lint trap and vent are clogged with debris

Tools and prep

• Screwdriver
• Vacuum with brush attachment
• Lint brush or old toothbrush
• Work gloves

• Ensure the dryer is cool to the touch

Step-by-step troubleshooting

1. Check and Clean the Lint Trap
   Do: Remove the lint trap and clean it thoroughly with a brush or vacuum.
   Observe: Lint trap is clogged with hair and fabric softener residue.
   Means: Blocked lint trap is causing the smell.
   Next: Clean the lint trap and run a test cycle.
2. Inspect the Dryer Drum
   Do: Wipe the interior of the drum with a damp cloth to remove any trapped hair or debris.
   Observe: Hair or fabric softener buildup is present on the drum walls.
   Means: Trapped debris is burning during the cycle.
   Next: Clean the drum thoroughly and run a test cycle.
3. Clean the Dryer Vent and Exhaust Duct
   Do: Disconnect the vent hose from the back of the dryer and use a vacuum to remove lint and debris. Check the exhaust duct outside the house for blockages.
   Observe: Lint and hair are clogged in the vent or duct.
   Means: Blocked vent is causing overheating and burning smells.
   Next: Clean the entire vent system and ensure it is clear.
4. Check the Dryer's Exterior Vent Cover
   Do: Remove the vent cover outside the house and clean it with a brush or vacuum.
   Observe: Vent cover is clogged with lint and debris.
   Means: Blocked vent cover is restricting airflow and causing overheating.
   Next: Clean the vent cover and ensure it is clear.
5. Inspect the Dryer's Interior Components
   Do: Open the dryer's back panel (if accessible) and check for lint buildup in the motor compartment or around the heating element.
   Observe: Lint is trapped in the motor compartment or around the heating element.
   Means: Lint near heat sources is causing the smell.
   Next: Clean the interior components and ensure no lint is near heat sources.
6. Run a Test Cycle
   Do: Plug the dryer back in and run a test cycle with a small load of clean, dry clothes.
   Observe: The smell returns during the test cycle.
   Means: The issue may be more complex and could require professional help.
   Next: Consult a professional appliance repair service.
