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 found. Fire risk is present.

• Inspect lint and ducts: Clean the lint filter, exhaust hose, wall vent, and internal ducts thoroughly. Remove any lint mats near the heater housing.
• Check heater housing: Access the heater and look for lint or fabric pieces touching the element. Remove any debris carefully.
• Inspect wiring: Look for discolored, melted, or burnt wiring, especially near the heater and motor. Replace damaged wiring and investigate the cause.
• Test run under supervision: After cleaning and repairs, run a short cycle while monitoring for any smell. If the burning smell persists, discontinue use and have the dryer inspected by a professional.
