No mist When I turn it on now there is no mist. When it stopped I replaced the cartridge

I have had times where my Crane humidifier won't produce mist if I haven't turned it on for several days (4+) or more. The water that sits in the reservoir may develop a film on the ultrasonic element which inhibits the creation of the mist to come out the top of your humidifier. I would lift off the tank and empty the reservoir. Then VERY GENTLY with a piece of paper towel, wipe the ultrasonic element (looks like a disk the size of a quarter at the bottom of the reservoir) to clean off any film. Then replace the tank and let the reservoir fill up the tank and try it again.

If your humidifier runs properly for a minute and then makes a whirring noise and goes silent (like the motor stopping), then it's a motor problem. The humidifier motor may have gone out of alignment due to bumping or rough handling of the humidifier when cleaning or emptying it. If that is the case, you will have to empty the humidifier reservoir, unscrew the base, and find the screws holding down the motor and check for misalignment. Loosen them a little and put it back together and try again.

Best of luck

does it have water in it

Ensure there is water in the tank.

• This may be caused by mineral deposits in the water channels. Try the following: Clean the water tank, base and vapor nozzel with a damp cloth to remove any build up in the water channel.
  
• When was the last time the cartridge was changed. (If it’s been over 3 months, this could be the reason why the unit is not working properly.)
  
• Unscrew the demineralization cartridge and run the unit, if it starts to mist then you need a new cartridge. (insert cartridge link here)
  
• The screw cap for the water tank, onto which one first screws in the demineralization cartridge, has a small rubber gasket. make sure that gasket is not too far down against the outer screw cap. If it is the spring loaded button would not work properly to let the water descend into the base tank .
  The solution: push up on that small rubber gasket so that it is as far up and away from the screw cap as it can be without falling off, and voila! you get mist!!
  
• If you have changed the filter recently then take out the cartridge and run the unit without the cartridge for about 15 to 20 minutes.

if it's a cool mist unit it will not produce any mist. now if it's a warm mist unit it should. that's normal. it is possible to replace the transducer if it is damage but you are going to have some leakage from it. but the only way to get the transducer mainly is from the manufacturer

i would try cleaning the coils for the heat portion. if they are to scally that could be one reason why it's not making any mist. but if it looks pretty clean or if you have cleaned it and it's still not making any mist then it's something internal. now if your under warranty still that's a good thing. you can always call the manufacturer and they can replace theunit for you under warranty . if you have any other questions please let me know.

unfortunately on a cool mist unit the mist shouldn't show up. on most units that's what it does. the warm mist units show the mist.. the best way to tell is if you put your hand over the spout that the mist is suppose to come out of for about 2 minutes and you pull it away and it feel clammy then it's working. if your hand is still dry please let me know and i'll see what else i can do for you.

Ours has done the same thing after only 2 weeks. From article research, it appears that this occurs to everyone after cleaning it with the EZ Cal that is recommended. From looking at our unit and figuring out how it works, it appears as though the Ultrasonic Vibration membrane has stopped working. This particular piece is responsible for vibrating the water and making water mist particles which are blown out with the air. We will be calling the manufacturer on Monday to register a complaint and request a replacement unit.

According to the Crane's Troubleshooting section:
The power light is green but there is no mist being emitted:
- Check that there is water in the tank.
- Check for possible lime deposits on the water level sensor or the nebulizer.
- Make sure that nothing blocks the vapor output slots.
- Check that the fan vent on bottom of humidifier is not blocked.
- Empty the humidifier and rinse the water basin with cool tap water and allow to dry for 15 to 30 min.

This next part may or may not be relevant.
Humidifier power light is staying red and not turning green. Or, Humidifier is working then stops:
- Ensure that water level sensor is assembled properly.
- Clean water float.
- Call service center and request replacement water float.

The grey circle (diaphram) needs replacing. Try Maplin electronics.

Soak it with vinegar for several hours then use a soft nylon bristled brush to scrape off the minerlized crust and rinse. You probably need to replace the silver stick & mineralization cartridge more often.
