Dryer has a burning smell during operation, sometimes accompanied by visible lint inside the cabinet.

Safety first: Immediately stop the dryer, unplug it, and do not continue using it until the cause is found. Fire hazard.

• Inspect lint filter and vent: Clean the lint screen and check the vent for blockages to ensure proper airflow.
• Open the cabinet: Remove rear and lower front panels. Carefully vacuum lint from around the heater housing, motor, and blower.
• Check for foreign objects: Look for items that may have fallen into the heater area or drum seal and are scorching (e.g., plastic, rubber).
• Examine heater housing: Inspect for signs of scorching or warped metal. If the element has sagged and touches the housing, replace the heating element assembly.
• Test run under supervision: After cleaning and repairs, run the dryer briefly while monitoring for any remaining odor. If burning smell persists, discontinue use and have a technician inspect it.
