Learn how to clean the vent safely and restore a clear airflow path.
If a normal load needs two cycles, a restricted exhaust path may be reducing airflow. Clean the lint screen, housing and duct, then check that the outdoor vent opens freely.
The vent carries warm, moist air outdoors. Lint buildup can slow that airflow, lengthen drying and allow heat to accumulate; clear lint from the filter after every load.
Damp clothes, unusual heat or humidity, and an outdoor flap that barely moves can point to a restriction. These signs are clues, not a diagnosis; other dryer issues can also slow drying.
Match the brush or flexible rod to the duct material and route. A tool suited to rigid metal may snag thin foil ducting, loosen a joint or get stuck if forced.
Empty the dryer, clear space and read its instructions before starting. Switch it off and disconnect power; follow the appliance guidance especially carefully for gas dryers or built-in units.
Remove lint from the trap housing and duct with suitable tools. Stop if the duct is damaged, hard to reach or the brush meets firm resistance; forcing it can cause damage.
With the dryer off, inspect the outside termination for lint, leaves, nests or a stuck flap. Clear loose debris without pushing it farther into the duct, and check that the flap moves freely.
Contact a qualified professional for a long, inaccessible or damaged duct, a blockage that remains after careful cleaning, or an outdoor vent you cannot reach safely.
Clean the lint screen after every load and check the outdoor flap periodically. Set duct-cleaning frequency according to laundry volume, duct layout, dryer instructions and inspection findings.
Lint can collect below the removable screen, so carefully vacuum the reachable housing with the dryer off. If care instructions allow, wash a residue-coated screen and dry it fully before reinstalling.
