Sunbeam ultrasonic humidifier runs but produces no mist

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

This humidifier is AMAZING. I’m a huge fan of using essential oils (lavender, lemongrass, spruce, rose, sandalwood etc) and I picked this up from a thrift shop, added some essential oils to the water and my house smells wonderful.

Essential oil diffusers are virtually the same thing design wise except cost a fortune. This is my best diffuser! I paid $10 for it and it works so good, throws off a ton of mist which I love (it’s so dry here) and I will enjoy owning this unit for years to come. Only thing is to gently clean the little ionizer part with the brush gently and keep it clean. Also..this unit unlike newer ones does NOT shut off automatically so keep an eye on it. Running it dry might cause it to burn out.

Same problem. It worked for about a week, then gradually stopped producing mist. No solution.

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?

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

Located My Manual:
Hope this helps!

1. Remove tank from base. Turn upside down and unscrew filling cap. Fill tank with clean, cool, distilled, or tap water. Water temp should NEVER be too hot or too cold. Return tank to base and let sit for a few minutes. Be sure the filling cap of the tank is tightened firmly.

2. Plug power cord into a 110-120V AC wall outlet only. Turn power switch to "on" position. Power light will illuminate. Turn mist nozzle until desired level is being released. Aim nozzle away from furniture and walls.

3. Always turn humidifier off when water runs* out. Unit will continue to operate when tank is empty.
*Humidifier will run up to 12 hrs on low; 6 hrs on high.

DO NOT LET WATER SIT IN TANK FOR LONG. THIS CAN ENCOURAGE BACTERIAL GROWTH.
Place unit on level surface away from direct sunlight.
DO NOT ADD MEDICATION OF ANY TYPE INTO THE NOZZLE, BASE, OR WATER TANK.
ALWAYS LEAVE ROOM DOOR PARTLY OPEN. DO NOT MOVE, TILT, OR EMPTY WHILE OPERATING.

Mild bleach and water solution for cleaning, never detergent.
Clean every 3rd day during use. Clean after long storage
Humidity varies from room to room. Aim for 30 - 50% relative humidity. If windows/ walls fog or frost, reduce mist intensity. If room too humid, ventilate by opening door or window; adjust mist intensity.

The Problem is minerals in the water. Impeller and ultrasonic designs send these minerals into the air. If the water in your area contains a lot of minerals, you will notice them as dust. The EPA does not issue health warnings about minerals in the air, but does recommend using low-mineral water (such as distilled water) in your humidifier. Many ultrasonic models feature a demineralization cartridge that filters minerals out of the water to prevent the dust.

Good Luck.

sounds like the small fan that is located in the base isn`t pushing the mist out. unplug it then take all the screws out of the base. there are screws under the black foam stands too. be careful not to touch anything that looks like live wires while you look inside then look inside while it is pluged in. it should turn. check for something blocking it like lint or dirt..you may be able to clean around the shaft with w d 40
