Dryer Not Collecting Lint

Quick answer

If your dryer isn't collecting lint, first check the lint trap and clean it. Then inspect the vent hose and exterior vent for clogs. Regular cleaning prevents fire hazards and improves efficiency.

Confirm the symptom

• Lint builds up on clothes after drying
• Dryer takes longer to dry clothes
• Excess lint around the dryer or vent area
• Smell of burning or overheating during use

Tools and prep

• Screwdriver (if needed for vent access)
• Vacuum with hose attachment
• Lint brush or old toothbrush
• Work gloves
• Turn off dryer power at the circuit breaker or unplug it
• Clear work area for lint and debris

Step-by-step troubleshooting

1. Check and Clean the Lint Trap
   Do: Remove the lint trap from the dryer and inspect for buildup.
   Observe: Lint trap is full or clogged.
   Means: Clogged lint trap reduces airflow and lint collection.
   Next: Clean the lint trap thoroughly with a brush or water rinse.
2. Inspect the Dryer Vent Hose
   Do: Locate the vent hose behind or underneath the dryer and disconnect it.
   Observe: Lint or debris is stuck inside the hose.
   Means: A blocked vent hose prevents lint from exiting the dryer.
   Next: Use a vacuum or brush to clear the hose. Reconnect securely.
3. Check the Exterior Vent Cap
   Do: Go outside and remove the vent cap from the wall or roof.
   Observe: Lint is clogging the vent opening or the flap is stuck closed.
   Means: A blocked exterior vent traps lint inside the system.
   Next: Clean the vent and ensure the flap opens freely.
4. Test Dryer Performance
   Do: Plug in or restore power and run a short drying cycle.
   Observe: Lint is now being collected properly and airflow is improved.
   Means: The issue was likely a blockage in the lint system.
   Next: If lint still builds up, inspect for deeper vent issues or consult a professional.
5. Inspect Dryer Drum Seals
   Do: Check the rubber seals around the dryer door for lint buildup.
   Observe: Lint is trapped in the drum seals.
   Means: Lint can escape into the room if seals are not clean.
   Next: Wipe or vacuum the seals to remove trapped lint.
6. Check for Vent Restrictions
   Do: Measure the length and number of bends in the vent system.
   Observe: Vent is excessively long or has too many bends.
   Means: Poor vent design restricts airflow and lint movement.
   Next: Consider shortening the vent or reducing bends for better performance.
