Good Afternoon, Our house humidifier has stopped working. That is since it was installed, it has hardly been used. I have noticed that the water is not flowing from the spout (taken from our water heater). There is a connection (like a thermostat) at the bottom of the humidifier where the water main and some electrical wires connect to. That seems not to be clicking and functioning. Am I to replace this unit or is there something else I should try to get it working? Regards, Cyrus

There could be several reasons why a humidifier stops running after refilling it with water. One of the most common reasons is that the humidifier's float switch is stuck in the "low water" position, which prevents the humidifier from turning on even after refilling it with water . Another reason could be that the humidifier's water level sensor is malfunctioning, which causes the humidifier to stop running even when there is enough water in the tank/

If you have a whole-house humidifier, it could be that the humidistat is set too low, which causes the humidifier to turn off even when there is enough water in the tank 1. Alternatively, if you have a portable humidifier, it could be that the unit's motor has burned out or that its fan has stopped working .

To troubleshoot this issue, you can try cleaning the float switch or replacing the water level sensor if they are damaged. If you have a whole-house humidifier, you can try adjusting the humidistat to a higher setting. If you have a portable humidifier, you can try replacing its motor or fan

I've never heard of a manually-filled furnace humidifier. We use a whole-house, stand-alone humidifier (manually-filled) and it works just fine. Easy to fill, easy to clean, easy to maintain. Even if there were such a thing as a manually-filled furnace humidifier, in the case you describe, I would much rather stay inside to fill my humidifier than get bundled up and step outside into the cold to do it. Hope you find a good solution. Good luck!

Here is a link to your humidifier http://www.iaqsource.com/article.php/my-aprilaire-humidifier-is-leaking-what-to-do-about-it./?id=35

Please have the selonid valve replaced.The coil is shot.

Hope this helps, check and see if humidistat is set to 35% humidity and that bypass damper on humidifier is in the open position or winter position.(humidistat is usually located on cold air return duct near furnace). Next, replace humidifier media pad, remember to replace media pad (filter) annually, you also may want to clean any lime deposit out of humidifier housing with a solution of warm water and white vinegar before installing your new media filter.Remember to turn power off at side of furnace when cleaning humidifier and replacing media. Before installing new media turn power back on to furnace, set humidistat to the on position, turn furnace thermostat above room temp., and inspect humidifier to see if water is running from top,(you may want to have a bucket under humidifier when checking for water), if you see water running, turn power back off to furnace, properly install new media filter, reconnect humidifier cover & set humidistat to 35%. If you do not see water present, check water supply valve to humidifier and make sure its turned on. If water supply valve is open, then check water supply tubing for blockage.And the last things to check is to make sure all registers through out your home are open and not blocked by any objects, also make sure furnace filter is cleaned, if none of this works refer to installation manual to see if humidifier was sized and installed properly, Good luck.

If the water continues runs nonstop even when the heater is turned off, you might have either a bad solenoid valve or a bad humidistat. Simply disconnect one of the two low voltage wires going into the unit. If the water turns off then your problem is most likely your humidistat or the low voltage wiring. If the water continues to run even when the low voltage is disconnected you have a defective solenoid valve.
Good luck.......

Hi, Hot will make the problem worse. If your calcium is that high you will have scale in your tubs, sinks and toilets. Calcium is a pipe clogger and if you have noticed this type of scaling you may be wise to consider a whole house water filtration system, it will save you lots of problems in the long run. Good Luck!

How long are you going between filter changes?

A filter that stops wicking water up and turns orange/yellow is one full of deposits.

It sounds like you have hard water. How are you filtering this water before you use it? Distilled water is the best.

Replace the filter. They don't last forever. Mine normally last a month to a month and a half.

Good Luck

Have you checked the position and function of the floats in the pan?

As the previous poster said, it's probably a problem with your water.

Are you using tap water or bottled mineral water? If so, there are minerals which get nebulized along with the water, and leaves a white, dusty, residue. I fill my Crane Pig humidifier with DISTILLED water, which is pretty pure. Make sure that the water is DISTILLED ONLY, since some of the water companies distill the water and then add minerals back in (they almost got me here until I noticed the label that said "with minerals added"). The reason this is important is because during the distilling process, the water is boiled, evaporated, and then the vapor is condensed back to liquid. This removes any impurities or dissolved minerals from the water. You can see Wikipedia for more on this topic here.

Additionally, I use both the Crane Demineralization Filter Cartridge (which works for the penguin as well, and gets installed in place of the original water tank cap), and the ProTec PC-1 Humidifier Tank Cleaning Cartridge (which I plop into the water tank) to keep the water both de-mineralized and bacteria free. I got both products at Amazon.com.

With these 3 things, so far I haven't had any white dust residue, and the mist feels fresh and clean.

On a side note, by using distilled water, you also prevent any mineralization from building up on the nebulizer or water level sensor, which can cause the humidifier to eventually stop producing mist...
