Humidifier is producing water but it is leaking and not going into bucket. Suggestions?


The only thing I can suggest is getting a new one. In theory, it should be possible to just fix whatever the problem is. In theory. However, should the problem repeat itself, it might come to the point where the total cost of ownership will outweigh the cost of getting a new humidifier. I would suggest something like the Honeywell HCM350W. It's a little bit bulky and you'd need to change the filters regularly, but it's a good and not very expensive humidifier.

Water refill light prevents unit from working. Tank is filled . Unit has been cleaned


Your problem is most likely a damaged Ultrasonic Disk (sensor).

If your product has not been used for a while, this piece was most likely damaged if it wasn't properly cleaned before storing. Cleaning well sometimes isn't even enough for this sensitive unit.
Unfortunately, there is no way to get this part, even though it is easily removed and could be easily replaced. Bad PR on the manufacturer's part. Your only solution is to send it for repair (if under warranty, you just pay shipping, if not, you pay shipping and $30) or to buy a different brand. You would think for as expensive as these machines are, the manufacturer would have a better solution to this extremely common problem.

The Hygrometer on my Air-O-Swiss U7142 reads 25% all the time. I assume its not functioning properly as I have other hygrometers in the house which say higher readings. Is there a known way to fix this? I...


I have got the same problem with my u7142 unit. This most probably means that the hygrostat inside is either broken or it has been heavily covered with the "white dust" in case the demineralization cartridge has not been changed for a long while.
To resolve it you have two options: either clean the humidity sensor or replace it. The sensor is at the bottom of the front panel, so you need to disassemble the front panel only, no need to open the whole unit (note that there are 2 screws at the bottom holding the front panel also). You need to get the sensor out from the printed circuit to open the cover and clean the surface of the sensor with something (blowing air does not help; you need physically touch the surface with something). If it does not help then you can go for the second option to replace the sensor, the type used in the unit is SYH-1. It is not a pricy element so you may go straight to the replacement if you find a shop nearby to buy it. I have simply replaced the sensor and now the unit is showing the proper humidity value and adjusting the steam automatically again.

V745a water valve does not work (will not allow water through), only have unit 2 months


the value would have been stuck inside the white cap, so when you press the stick with the spring, the head of the valve should stick out. If this does not work, just remove the spring and the black stick from the value, water should come out

I need to get about 70% humidity in my walk in humidor,so how do i adjust the kenmore humidifier


If you do not already have one get a cheap hygrometer at Lowes or Home Depot and put it in your humidor at eye level. Then run your unit until it reads 70 percent. When the unit is balanced in other words shuts off at that humidity you are set. Use a majic marker to mark the position and you are done. Let me know how this works out.

No matter what setting is put on furnace humidifier, moisture forms on windows.House is only 6 years old and does have a lot of windows.


Hello WPwilkers, Well there's good news and good news!

First off, you should probably use the lowest possible setting as your house being so new, is likely pretty "air-tight" and as such, doesn't have a lot of air infiltration (gaps and drafts) hence the reason you're seeing moisture on the windows.

Now, I would also use a hygrometer, just like your parents likely had hanging on a wall somewhere in their house. It will give you a better idea of the moistur (humidity) around the house. My guess is that you're already at the 60%+ level of humidity.

I suggest that you turn "OFF" the furnace mounted humidifier, until you no longer see moisture on the windows. That will allow the house to adjust and get back to normal humidity levels.

Then you can start by setting the humidifier on the lowest possible setting and keep an eye on the moisture levels in your coldest room of the house, as that is where you'll first notice the excessive moisture on the windows (just the way it works - cold rooms get condensation on the cooler windows first).

If you don't have the humistat (the control for the furnance mounted humidifer) mounted next to your heating and cooling system thermostat, you should do that - it will make it easier to adjust and also will provide a more accurate reading for the humifier to operate properly.

Some Thermostats have the ability to add a humidifier on it for integrated controlling of the furnace humidifer. Check your Thermostat and Furnance owner's manual for details.

I used to have the same problem and found that by moving the humidifer control from the utility room (mine was in the basement of my house) to the living space, it made a big difference. Since most people's homes have unfinished basements and that's where the HVAC system is located, it doesn't get the same humidty readings as an occupied living space.

The other reason that you tend to get moisture (condensation) forming on windows is that the Percentage of humiditfication is set manually with the humidifier control, and yet, the outside (and inside) air temperature vary and the difference between them can cause the humidity levels to go from very dry to very moist, in a day or two.

I tend to wait until I notice that the air inside the house is getting dry and then turn on my humidifier, once the cold winter days have taken hold. In summary, nothing wrong with your unit, just mother nature and a well built (most air-tight) home are giving you higher levels of condensation than most older homes. Gradual adjustments, once you turn the humidifier off for awhile, should get you the desired results.

I hope you find this Very Helpful and best regards!

Mod#BLU100K948A The 2 selenoids on top of gas valve click when they open (normal). Sometimes they work fine, sometimes they have a rapid clicking noise and do not open the gas valves. Furnace just runs and...


The first thing to check would be the filters in the house to make sure they are clean, then check for any blockage. One easy way of seeing if the airflow is good, just put your hands in front of a vent and see how its blowing. Your furnace has what you would call sensors, and if they sense the air flow is inaccurate or to hot inside the unit, the unit will run, but not light. Also, if it tries to relight to many times, the furnace will go into lock out and you have to manually reset it by cutting the power to the furnace. Its kinda hard to diagnose these sometimes over the pc, but I hope it helps.

My honeywell humidifier is using water at 2 gallons an hour


Furnace mounted humidifiers "should" be wired so that they are only running when the furnace blower is on. When the furnace is off so should the humidifier. If it is wired proper, it is possible that you have a bad solenoid valve. It could be stuck in the on position. If it is bad these valves can be expensive. If your humidifier is newer, fix it. If it is old you are probably better off to just buy a whole new unit.
Good luck

Aprilaire 600 just installed and showing an error code


No, it is not an accurate statement.

These units have simple configurations They have a water supply similar to a ice making referigerator, an enclosure connected to your supply duct that houses a prop fan and media, a seperate humidistat and a drain for excess water. Your unit may also include fancy controls including an outside thermometer & humidistat to avoid over humidification that can cause problems during freezing weather. The humidistat looks a lot like a thermostat and is located in your living space or in the return duct. The prop fan in the box pulls air from the duct, through evaporation media and back to the duct. An electric solenoid valve releases water that pours over the media.

If the humidiy is below the humidistat seting and the AC/heater is running, the Aprilaire fan starts and the solenoid valve opens. I suspect the facier controls include the flashing warning light.

The warning light spells problem. Aprilaire's customer service should be able to provide guidance for the homeowner in the form of simple checks. I suspect your contractor is avoiding a warentee call and the trip it requires.

A word of caution. These humidifiers can be powered directly from your air conditioning unit control board from an auxiliary connection. If the control board isn't rated to carry the current required by the Aprilaire fan, valve and controls or the Aprilaire encounters and electrical problem, the board can be damaged. This can be avoided by using a relay. The AC board switches a low energy relay. 120 volt house power is connected to load side of the relay and runs the Aprilaire.

My board cooked at a location near this connection, but I can't be sure that the load from the humidifier caused it since four of our neighbors also lost their board. It failed the evening of a snow storm and required a costly emergency after hours service call. The next day a new board required a three hour drive. Fortunately a fan powered propane heater kept our pipes from freezing.
