The dryer takes too long to dry; multiple cycles are needed; outside vent airflow feels weak; no error code is displayed.

Safety first: Unplug the dryer before removing panels.

Steps:

• Clean lint filter: Wash with warm, soapy water to remove film; dry completely.
• Inspect vent hose: Shorten and straighten the exhaust hose; replace it with rigid or semi-rigid metal duct if flexible foil is used.
• Clean house duct: Use a vent brush kit to clean the duct leading to the outside.
• Clean internal ducts: Remove the rear panel and vacuum lint from the blower housing and internal ducts.
