Dryer emits a burning smell during operation (no error code).

Safety first: Immediately stop the dryer, unplug it, and do not use it again until the cause is identified. Risk of fire.

• Inspect lint filter and ducts: Clean the lint filter thoroughly. Check the exhaust hose and wall vent (vented models) or condenser/heat exchanger (condenser/heat pump) for heavy lint buildup and clean completely.
• Check heater area: Remove the rear panel to inspect the heater housing. Look for lint deposits on or near the heater and remove them carefully with a vacuum and brush.
• Look for foreign objects: Inspect inside the drum and around the heater for plastic items, labels, or fabric pieces that may have come into contact with hot surfaces.
• Inspect wiring and motor: Check for burned insulation or melted connectors near the motor and heater. Any signs of electrical burning require component replacement and possibly professional inspection.
• Test cautiously: After cleaning and repairs, run a short cycle under supervision. If the burning smell persists, discontinue use and contact a qualified technician.
