What happens when this humidifier runs out of water? Is the motor history? What do you do?

When the water level is too low, the sensor will shut off the motor and humidifying device. And "add water" indicator will light up. All you need to do is refill the water tank. Once the water level goes up, the functions will start again. If you have any additional question, please contact SPT at 1-800-330-0388 or initiate another question here.

Air has to move thru the humidifier. This happens from the furnace blower. You can run the fan motor without heating or AC. For my application I purchased the relay shown as an option. Makes the install easier.

Is the tank full? If yes, it is time to change the water filter. To troubleshoot: remove the water filter (it unscrews from the tank lid) and try without the filter. If it works fine the filter is clogged and needs to be replaced. These filters become slower with time and after a few months of heavy use they don't let through enough water to keep up with the needs of the humidifier. This year, I had two of those filters be bad right out of the package (they did not let through enough water even when new) and I had to exchange them for new ones (thanks Amazon for making this so easy!). By the way: it is perfectly fine to operate the humidifier without the filter, at least temporarily, but there is more white dust on all surfaces when there is no filter installed and the silver ions in the filter keep the tank from getting all slimy and stinky.

You did not do anything wrong. My unit worked the first time or two and then leaked from the bottom. I believe the humidifiers are poorly designed.

Unfortunately, while this is a decent humidifier, what you mentioned is an annoying problem with it. I have bought two and have the same problem.

I would suspect that yes, you need to replace your humidistat. I have an Aprilaire humidifier and my digital humidistat went bad. Since my humidifier was aging, I replaced it also. I went back to the "manual" humidistat since it's simple and no electronics to go bad. The only thing the digital humidistat buys you is an outdoor temperature sensor (thermocouple) that automatically adjusts the setting based on the outdoor temperature ...sounds good but not that big of a deal. I set my manual humidistat a couple times ...when I expect the temperature to routinely get below 20 deg and then when I expect it to be above 20 deg. Never had a problem with that. Good luck!

Mine quit pumping water but I had no idea why. It just sat there making a spinning sound. I threw it out tho I did order another for when I travel. I chose to go back to my full size Waterlpic with the nasal adapter for use at home.

I would say that your unit is defective, yes. I used my humidifier all last winter in my office, and never had this problem.

I am under the impression that you should not run it dry. I unplug mine as soon as it "sputters" when emptying a water canister.

As noted on other responses, unplug at the bottom back and tilt the machine. To be honest I have not run it long enough to build-up any water due to poor performance.

I had the same problem... within the first week. Packed it up and sent it back for a refund.This is my second Venta humidifier. My first one lasted three years with daily use. I loved it. Would not buy another.

Clean it out completely and check cords. Also make sure there is water in it, If not it may slow down or stop without it. Mine did that, but after I cleaned it and filled it back up, it was up and running. I think it's because the water was too low. That makes sense to me.

This humidistat runs off 24V AC and often has it's own step down power supply when the blower board doesn't support it. Check if you are getting 24V AC coming up to the humidistat. The solenoid for the water should be closed unless the blower motor comes on. The transformer is hooked directly at the blower board for aux power 115V. Check your manual for the diagram. If it's blowing the breaker, the blower board is probably detecting a problem with the step down transformer 115 to 24 AC. I'd be checking there. The humidistat acts like a light switch and that's just a simple circuit, open or closed. When you turn the knob you can hear it click, that's opening and closing the circuit to directly to the water solenoid. If the solenoid is stuck open, the solenoid is probably blown. The people who installed ours (before we bought the house) hooked it up without the 24V AC step down. 115V directly to the solenoid and poof it's gonna blow. When it blows, its stuck open leaving water constantly flowing. Here are two links to products that are comparable to what I referenced. Hope that helps.

Mine started with a high pitched buzzing noise and now after 4 months the motor is not running right and mist output is low. I am having it replaced as I like the features. If I get one that works and does not make the noise, I will be very happy! :)

I would not recommend this product. The problem was with the humidifier. The 2L plastic they suggest using, collapse on themselves and then leak all over. Thinking I had a defective unit I returned that one for a new one. Same problem. Even though you wouldn't mind the water on your roof, the water would empty out and you would have no more mist. I bought this unit from Amazon and think it's great. The only drawback is the smaller water vessel. But that no big deal. My model is: Lasko 6462 and was purchased from Amazon. I hope this helps.

I always run mine until it runs out of water. Did you chech to make sure the power cord was attached properly? You also need to check that you didn't overfill it. Mine won't run with too much water.

I would contact Essick. Last year my humidifier didn't work but just groaned when I first started it. It was only the second year I'd had it. I called Essick and learned that the year before, the motors were defective in a group that had been sold. Because I had my receipt which I faxed to Essick, a new humidifier was sent to me a no charge. It worked well last season and is working well this season with new filters. I doubt that your problem is a filter issue. Good luck.
