Dryer emits a burning smell during operation, with or without visible smoke.

Safety first: Switch off the dryer immediately, unplug it, and do not use it again until the cause is found. If you see smoke or flames, evacuate and call emergency services.

Inspection:

• Remove the lint filter and check for heavy lint build-up; clean thoroughly.
• Remove the rear panel and inspect the heater housing for lint accumulation or foreign objects; vacuum and clean carefully.
• Check wiring around the heater and terminal block for signs of burning or melting; repair or replace damaged wiring.

After cleaning and repair: Run a short supervised test cycle. If any burning smell persists, stop using the dryer and contact a professional technician.
