Possible Causes

Lint buildup on heater, Foreign object touching heater, Overheated wiring or connector, Blocked airflow causing excessive temperatures

How to Fix / Troubleshooting

Safety first: Turn off and unplug the dryer immediately if you smell burning. Do not use the appliance until it has been inspected.

  • Inspect lint filter and condenser: Remove all lint from the filter and condenser. Blocked airflow can cause overheating and burning smells.
  • Check heater area: Remove the rear panel and inspect the heater housing for lint buildup or foreign objects. Clean thoroughly with a vacuum and soft brush.
  • Inspect wiring: Look for discoloured, melted, or burnt wires and connectors, especially near the heater and terminal block. Replace any damaged wiring and connectors.
  • Check drum seals: Ensure felt seals are intact and not dragging against the heater housing.
  • Test run under supervision: After cleaning and repairs, run a short cycle while monitoring closely. If the smell persists, stop the dryer and seek professional service.
