Dehumidifier with built-in humidifier function (on some Pro Breeze models) does not produce mist.

Safety: Unplug the unit before servicing the humidifier section.

Steps to restore mist production:

• Check water level: Ensure the humidifier tank is filled and properly seated on its base so that the valve opens.
• Clean transducer: Access the humidifier base and locate the ultrasonic transducer disc. Gently clean mineral deposits with a cotton swab and white vinegar, then wipe with clean water.
• Inspect water level sensor: Check the float or electronic sensor in the humidifier reservoir. Make sure it moves freely and is not stuck.
• Replace transducer module: If the unit powers on but no mist is produced even after cleaning, replace the ultrasonic transducer module or humidifier base assembly as specified for your Pro Breeze model.
