Honeywell HE360A1027 Whole House Humidifier Humidifier - Answered Questions & Fixed issues

The replacement solenoid may have been defective.

yes water should turn off solinoid is bad

If you are keeping your humidifier set to 76, this is far too high. A humidifier setting of 40 to 50 percent is about right. Depending on your window insulation, you may have to reduce the setting in very cold weather if you start getting condensation on or around the windows.
Hope this helps.

Use mini RO system or good filter to feed humidifier with water that contains less minerals.

Try to disconnect the main power to the unit and if the water valve is still open and water is running, you have a bad valve (the valve stuck open). Tap on the valve body it may help on sticking it, if not replace it.

I'm not sure what wiring option did you use, but looks like you did not include pressure or sail switches... When the furnace blower/fan is off it should open the 24volt circuit and close the water valve (normally close) and turn off the fan. If you can post more wiring details maybe pictures or hand sketch I'm sure problem can be fixed in the few minutes.

If humidifier is running but water valve is not clicking open, check the wire connections. If connection is OK, than unplug the humidifier from 120V outlet, disconnect water valve wires and with multimeter check resistivity on the valve coil. If the coil is burned out/open/no resistance, the coil needs to be replaced.

Yes. Make sure to connect to HOT water line for better performance.

Check yor wiring, make sure you have sail or pressure switch wired in series with humidistat to humidifiers 24V power. Pressure or sail switch will disconnect humidifier when furnace fan is off. Humidifier (110V) could be connected to any closest electrical outlet.

Follow the provided web link. Select from the appropriate category of humidifiers by Essickair, then click on the "More Info" link after which you should choose the specific model humidifier that you own. After doing so you will find a link to the lower right(under "Resources") saying "Owners Manual."Clicking that Owners Manual link will allow you to open and/or save your humidifiers manual.

It's not uncommon for duct work in an older home to Bang as the furnace cycles due to age. The humidifier banging while turning on and of is mostlikely the solenoid valve; if the solenoid is bad it is actually to your benefit to replace the entire humidifier as the solenoids are very expensive, 50%+ of a new humidifier. Plus you get the 5 year parts warranty on the new unit instead of just one year on the solenoid. If you don't want to replace the entire unit you can replace the Humidistat, and that should fix the on/off cycling, however a new humidistat is included with a new unit, which again is more cost effective. They are easy enough to replace as a do it yourselfer, especially when replacing an existing unit. I hope this helps you.

I have a similar problem with mine too. I am interested to see if anyone can diagnose this problem

Hello, usually the transformer will burn up when the amp rating of the transformer is being exceded or if there is a short in the low voltage wiring

Hello, if you are getting 24 volts to the solenoid valve and it is not working replace it. However, if you are not getting 24 volts check the humidistat, transformer, and wiring.

Hello, if you have a email adress I can email you the diagram in a PDF file

Hello, typically it should take about a hour and a half to install a humidifer, usually takes me an hour and a half to two hours to install one. Anything over two hours is too long.

The humidity level setting may be set to low. 40% is right for most home environments. However, you made need to set yours at 50%.

Hello, is there water going down the drain tube, if so then the humidifier is working. The pad does not really get saturated the water just trickles on the pad and the the fan blows it into the air duct. your outside air temp determines what your humidistat should be set at.

Outside Temperature -10 F 0 F 10 F 20 F 30 F Recommended Indoor
Relative Humidity 20% 25% 30% 35% 35%

Hello, in order to turn your humidifier on with the furnace the 120 volts coming from your humidifer you must hook it up to a step down transformer, then the transformer will provide 24 volts to you humidistat and solenoid valve. So you need a wire from the HUM on your control board to transformer primary side and a wire from neutral on the board to primary side of transformer. Then you need low voltage wire from secondary side of transformer to humidistat from humidistat to humidifier.
