Dryer emits a burning smell during operation, even though it appears to work.

Safety first: Stop the dryer immediately, unplug it, and do not continue using it until the cause is found.

• Clean lint filters and ducts: Thoroughly clean the lint filter, condenser (if fitted), and any accessible ducts.
• Inspect heater area: Remove the rear panel and visually inspect the heater housing for lint buildup or foreign objects. Carefully vacuum around the heater without damaging coils.
• Check venting (vented models): Ensure the vent hose and external vent are clear to prevent overheating.
• Test run under supervision: After cleaning, run a short cycle and monitor for smell. If burning odour persists, discontinue use and have the heater and wiring inspected professionally.
