I've had this for a month and it stopped blowing mist. It ran completely dry last night and I cleaned out the reservoir with the brush and rinsed with warm water from the vegetable sprayer in the kitchen. Now when I turn it on, the fan blows air but there is no mist. Help!
unplug humidifer, remove top tank, empty all water out of base. dry off.
turn unit upside down.
unscrew five visible screws.
use a screw driver to pull off the black foam foot pads. you will find more screws there.
pull off the base.
look next to the fan, you will see a metal "tower" going up into the reservoir. Is it dirty such as white chalky substance on it? Clean it with cotton swabs. Clean the fan while your at it if needed.
You will see a small gray box with two metal tabs twisted. Untwist them and pull off the top.
On that metal "tower" you will see a small black chip connected to the circuit board where you just removed the metal top. Does black chip have black marks on the circuit board? Mine does. I suspect the "tower" which draws heat from this black chip was no longer able to cool because of the white chalk buildup on the tower, furthermore, the chip became too hot and caused the black chip to overheat (again black marks on the circuit board).
The chip has on it "FTR 02N" and a "54F" at the bottom. I tried doing some basic searching on internet to see if it could be replaced, but didn't find anything.
For those who don't have this problem yet, just keep that metal cooling tower clean.
FTR 02N is simply a high frequency transistor. Try to replace it to another type. I have seen FTR 02N in my ultrasonic nebuliser (it's now working. I think ideal solution is replace all generator circuit. connect a 5 Ohm resistor parallel to the piezoelectric us emitter. Then find simple circuit of negative differential resistor, connect it in series with the emitter to adjustable power supply, then adjust voltage for maximum generating.

Tank is full. ... for about another 5 minutes when the unit stops, reset light comes on etc. ...the humidifier since the reset light keeps going on immediately after I turn ... water in the tank because of course, the heater is on, but no water is getting ...
If the water has been sitting in the reservoir for days without use, it 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.
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.
I have this same problem. And cool mist humidifiers DO produce mist. I have had my humidifier for a while now (6 years) and have never had any problems. But after the most recent cleaning, it worked at first, but now seems to not be working anymore... Am also wondering if there is anything I can do to remedy the situation?
I had the same problem. This will cause the orange reset light to turn on as well. You need to remove the reservoir and the cooling chanber. Under the reservoir there is a locking mechanism that you push to the side. You then pull off the cooling tower. Then you push the locking mechanism in the other direction and remove the steam mechanism. I found a month of build up of "gook" inside. Dump it out and use a scrouring pad to remove it. After this was done, I could smell the vapor from the medicine cup again and it ran all night on the high setting again.
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.

I haven't had any problems with my Vicks Cool Mist Humidifier other than the fact that the area surrounding it is slightly wet after operating for a couple of hours....While I understand that I was using this to moisturize the air during a cold, I knew this would happen, because the air in my room is not dry. If the room isn't dry, the mist that it's putting out in to the air has no where to go but surround the humidifier. All I did to stop this was to buy a water proof mat. I suggest you do the same -- Also, in regards to the water smelling -- You should be cleaning out and drying the basin after every use. Water shouldn't smell unless you let it stagnate inside the plastic -- Try running distilled vinegar through the machine for a couple of minutes -- Also, I would use an extension cord and let it run outside so that your house doesnt smell like Vinegar.
