Dryer runs but takes excessively long to dry clothes; laundry is still damp at the end of the cycle, no error code.

Safety first: Disconnect power before cleaning internal ducts.

• Clean lint filter thoroughly: Remove and wash with warm soapy water if coated. Dry completely.
• Inspect exhaust hose and wall vent: Remove the hose and check for lint buildup or crushed sections. Clean the hose and wall vent hood.
• Clean internal ducts: Remove rear or lower front panel and vacuum lint from blower housing and ducts. Avoid damaging sensors.
• Check load size and fabric: Avoid overloading and mixing heavy items with light ones; this can extend drying time.
• Verify heater operation: During a cycle, feel the exhaust air. If only mildly warm, test thermostats and heater as in the no-heat procedure.
