Quick answer: Turn the dryer off and remove the lint screen. Vacuum or brush only the lint you can see and reach inside the screen housing with a tool that cannot break or fall in. Do not remove panels or push lint deeper. If airflow is restricted, the dryer overheats, or lint is packed farther inside, stop and call a qualified professional.
The screen is not the whole lint path
The lint screen catches a lot of loose fiber, but small amounts can still collect around its frame and inside the housing. That is especially easy to notice when the screen is brushed clean but the slot below it still has a fuzzy edge.
A reachable housing clean can help remove loose surface lint. It is not the same as cleaning the full exhaust duct, checking the outside termination, or opening the dryer cabinet. Keeping that boundary clear is the safest way to use a narrow brush or vacuum attachment.
Prepare the dryer
Switch the dryer off and let it cool. If you are going to reach beyond the screen opening, unplug the appliance when the outlet and cord are safely accessible. Remove the lint screen and inspect it against the light. If the screen is torn, warped, or coated with residue, follow the manufacturer’s replacement or cleaning instructions.
Use a flashlight, a vacuum with a narrow attachment, and a flexible lint brush made for the purpose. Do not use a coat hanger, knife, screwdriver, or another rigid improvised object. A tool that can scratch, snag, or detach inside the dryer is not a good cleaning tool.
Step-by-step
- Vacuum the opening. Start at the rim and remove loose lint you can see. Keep the nozzle steady instead of jamming it down the slot.
- Brush the near surfaces. If the brush fits without force, move it slowly along the sides and bottom of the housing. Pull it back out to remove lint rather than pushing it farther in.
- Check the screen track. Wipe the rails or frame where the screen sits. A screen that cannot seat correctly can let more lint pass around its edges.
- Clean the screen according to the manual. Some residue can reduce airflow even when the screen looks empty. Use only the method recommended for that model.
- Reinstall and inspect. Make sure the screen is fully seated. Do not run the dryer with the screen missing.
Stop before opening the machine
Lint visible behind an interior grille, a smell of burning, unusual heat, a drum that stops, or a new scraping noise are reasons to stop. Do not remove the dryer’s front, rear, or side panels unless you are qualified and the manufacturer’s service procedure calls for it.
If the outside vent flap barely opens, drying takes much longer, or lint is collecting around the exterior termination, the issue may be in the exhaust path rather than the lint-screen housing. Arrange the appropriate inspection instead of trying to solve a whole-vent problem from the screen opening.
How often should you check it?
Check the lint screen after every load. Look into the housing when you see a visible rim of lint or when the screen no longer slides in smoothly. The calendar matters less than the condition of the path and the instructions for your dryer.
