Dryer takes too long to dry; multiple cycles needed; outside vent airflow feels weak; no error code.

Safety first: Unplug 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 with rigid or semi-rigid metal duct if flexible foil is used.
• Clean house duct: Use a vent brush kit to clean the duct to the outside.
• Clean internal ducts: Remove rear panel and vacuum lint from blower housing and internal ducts.
