What should the heating element look like after I've cleaned the buildup? I am doing this for the first time in a few months and the buildup is thick.


The heating element casing on which the buildup grows is made of an aluminum alloy that is originally black anodized which looks like plastic, but you should take care to not scratch the protective black anodize because over time it will corrode and makes a rough finish. It is not important to remove all the scale on the eating element, but only what falls off. You may let the element soak into vinegar or "CLR" cleaner from within the humidifier underneath pan such that would not need to scrub as it will dissolve and fall off. You have to rinse the pan and the eating element after soaking. If the layer of scale left is a thin that is OK, the water will go through as it is porous so the humidifier will continue to work normally. Keep in mind that the eating element is designed with a thermal protection built-in such that if the layer of scale is too thick to transfer the heat into the water, it will shut down by itself until it has cooled down enough.

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.

I have a aprilaire 600A I have hooked it all up but for some reason the number display doesnt show anything. The controls all light up, but no display. Also for some reason no water is coming out.


Thank you for contacting us. Does your humidistat have a blower activation switch on the lower left hand side of the humidistat? If you do it is our #60 humidistat, and if it is not there you have a #58 humidistat. The R & C are the two connections that supply power to the humidistat to give you the numbers on the digital display. The 60 you wire right into the R & C off the furnace panel. The 58 you need a constant 24 volt and 10 VA power source which you could get by using the transformer off a constant 120 volt power source to power the humidstat. If you are doing this correctly and you still do not get the numbers to show up, then you have a bad humidistat and you need to go back to where you purchased it from and exchange it under warranty provided you used a certified HVAC contractor to do the installation. Our warranty is only valid if you used a certified HVAC contractor to do the installation. If you have any additional questions please contact us at 800-334-6011.

Thank you

Start switch doesn't work


the switch is bad or there is a loose wire connection, if you have a multi-meter you can check the resistance on the switch, it should be 0.0-0.2 if the switch is good it could be the pump.If the pump is bad don't bother fixing it.

It would appear to me that you have lost the 24 volt power supply to the thermostat. In referencing the manuals for this thermostat, available @ www.honeywell.com, I've found that when the thermostat is not connected to the wall plate (plate mounted on the wall, that the thermostat either snaps or screws into), it will display the -AC. This being said, either the thermostat is loose on the wall currently, or your 24 volt transformer has died. Hope this helps.

Venta-sonic VS 207 humidifier. Turns on but the display just flashes lights. I had it stored all summer (followed the manual instructions) and it's the first time I'm turning it on.


I had the same problem. During the cleaning process, the white float was installed upside down and humidifier water level sensor was unable to read the float. I removed the phillips screw and inverted the float with the dark ring toward the bottm. Quick fix.

Thermostat - Honeywell Chronotherm III


What you can do is try and clean the contacts. Open the door on the thermistat and remove the two screws, after that you can seperate the part that is mounted to the wall and the front panel. Look at the part that is mounted on the wall and you'll see the contacts that should be a copper color. They might be black from age. Clean them and you'll be surprised how well it will work after that.

Honeywell Humidifier HUT102m


I've been having problems with this unit since purchase in December 2007.

To fill, unscrew the cap with the spring loaded plunger. It may be tight, but it has two slots which you can turn like a screwhead using something wide enough (eg, a spoon) for leverage.

My problem is that this thing leaks badly. The fit of the cartridge is terribly designed. The one supplied is different from the one depicted in the unhelpful manual, which is silent on where the cartridge should fit. It will fit in one spot, but it will not sit flush with floor of the unit; it rocks and the water holding top rocks with it. The supplied cartridge appears to be an attempted and unsuccessful fix of a problematic design.

Even without the cartridge, this unit still leaks.

A web search shows others complaining about leaking. Hate to say it, but another example of lousy American design... but it sure is pretty!

Haven't been able to raise the manufacturer "Kaz" on the phone.

Good luck!
