Humidifier runs but produces little or no mist.

Safety: Unplug and empty the tank before cleaning. Do not operate the humidifier without water.

Steps:

• Check water level: Ensure the tank is full and properly seated.
• Clean transducer: Gently clean the ultrasonic transducer disc with a cotton swab and white vinegar to remove scale, then rinse and dry.
• Clear mist outlet: Inspect the mist outlet and internal channels for dust or mineral deposits and clean with a soft brush.
• Verify fan operation: Ensure the internal fan is running; if weak or not running, replace the fan motor.
• Replace transducer: If cleaning does not restore mist, replace the ultrasonic transducer assembly.
