Dryer produces a burning smell or hot plastic odor during operation.

Safety first: Immediately stop the dryer, unplug it, and do not continue using it until the source of the smell is identified. Fire risk is present.

• Inspect lint filter and ducts: Clean the lint filter and inspect the filter housing for trapped lint. Remove rear or front panels to check internal ducts and heater housing for lint accumulation.
• Look for foreign objects: Examine the heater area for melted plastic, rubber, or fabric that may have contacted the element. Remove any debris carefully.
• Check wiring: Inspect wiring near the heater and motor for discoloration, melting, or burnt insulation. Replace damaged wiring and investigate the cause.
• Test thermostats: Verify that high-limit thermostats and thermal fuses are intact and not bypassed. Replace any faulty safety devices.
• Do not ignore persistent odor: If the burning smell continues after cleaning and inspection, discontinue use and contact a qualified technician.
