Washer-dryer combo emits a burning smell during drying or high-temperature washes.

Safety first: Immediately stop the cycle, unplug the unit, and do not use it again until the cause is identified. Risk of fire.

• Inspect lint paths: Once cooled, remove panels to access the dryer heater and ducts. Vacuum lint from around the heater, fan, and condenser.
• Check belt and motor: Inspect the drive belt for glazing or burning and the motor for signs of overheating. Replace worn belts and have a technician evaluate a hot-running motor.
• Examine wiring: Look for burned or melted connectors, especially near the heater and motor. Any damaged wiring should be repaired or replaced by a qualified technician.
• Call a technician: Burning smells should be taken seriously. If you cannot clearly identify and correct a minor lint issue, arrange professional service.
