Clean every user-accessible dryer lint filter as directed
Lint blocks airflow and can contribute to overheating and fire even when a dryer is ventless or uses more than one filter.
When it usually needs attention
Ongoing home-care habit
CPSC calls for cleaning the lint screen with each load; the exact manual identifies every screen and any additional care for the dryer design.
When this guide applies
Applies whenever a clothes dryer is confirmed, including ventless designs; extra filter stages remain model-specific.
What to do
Before or after each load as the manual directs, remove lint from every homeowner-accessible screen, reinstall each filter correctly, and leave deeper or damaged parts for service.
Applies when: Applies whenever a clothes dryer is confirmed, including ventless designs; extra filter stages remain model-specific.
Who should handle it: Residents handle only the user filters shown in the exact manual; concealed exhaust, heat exchanger, gas, wiring, and internal cabinet work belong to the responsible owner and qualified service.
Tools
- Exact dryer manual
- Hands or a manual-approved soft brush for the removable screen only
Parts and supplies
- Waste bag for dry lint
Safety gear
- Well-fitting mask if ordinary dry lint causes irritation
- Gloves if needed for ordinary dust
Before you start
- Identify every user filter in the manual
- Confirm each filter is fully seated before operation
Power, water, or fuel shutoffs
- Turn the dryer off and let it cool before removing a filter
- Do not open a service panel
Cleaner or chemical limits
Use no spray, solvent, fragrance, degreaser, dryer-sheet coating remover, or water unless the exact manual permits it for that removable filter.
Stop and get help when
- Stop for a torn or missing filter, lint beyond the user compartment, overheating, burning odor, scorch marks, spark, repeated shutdown, damaged cord, or any need to move the dryer
- Do not run the dryer without every required filter installed
Who to call: Keep the dryer out of use and use qualified appliance, gas, electrical, or exhaust service for internal lint, damage, overheating, or installation concerns.
