Re: water not running through humidifer

Mine had the same problem no water through the solenoid. It turned out to be the little adapter with the needle hole on it, attached to the solenoid on the intake side. It was clogged, cleaned it out and works great now.

He360 fan and water run continuously

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.

Wire Honeywell HE220 to N8MPN/L, *8MPN/L furnace control board


I have similar isssue with HE220 but in my case the water run through all ththe time, even when unplugged from the power outlet.
Would that be solenoid issue?
the unit run fine for last season so the wiring is fine.

Any ideas would be greatly appreciated.

I hooked the humidifer up and water keeps running it dose not stop when furnace stops. What might be wrong?

Hello, this could be tw o different things. when you install a humidifier you need a means of turning it on and off with the furnaces blower motor, this is done by either a sail switch, current sensing relay, or by the transformer being hooked up directly to the furnaces control board. if you do not have one of those three than the humidifier will run continuously untill u manually turn it off at the humidistat. If you have one of those three installed already than the solenoid valve is stuck and must be replaced.

The water runs constantly, not just when the furnace turns on.

Do you have a sail switch or current sensing relay with this humidifier? In order for the humidifer to turn on and off u need either a sail switch that senses airfllow in the return air duct and will turn off the humidifier when the blower motor stop or a current sensing relay that senses current on the blower motors common wire. I will post of pic of each one

Yes - but it doesn't have to work that way. There are several methods you can use to have the humidifier run only when the furnace runs. Look on the back page of the installation instructions. The method I chose was to install a sail switch. This is a switch with a arm attached which has a "sail' attached to it. When the furnace blower runs, the sail catches the blower airflow and activates the switch; allowing the humidifier to operate.
You can also wire in a current sensing relay (figure 6 on the instructions) or connect the humidifier directly into the furnace motor ignition box (if so equipped. My furnace dates to the late 70's and has no place to plug in a humidifier; which is why I installed a sail switch.)
Now however I probably would go with the current sensing relay option as this looks to be the easiest route to follow. Honeywell has their 32001754-001 avaliable for less than $35 from Sears.

I just finished hooking up my new he 220a HUMIDIFIER

I have a HE220, HE 260 pass, flow thru. There is no water flow between the hot water tank and the humidifer. The water valve is on. Is there an inexpensive part I can replace myself first before calling a plumbing contractor?

My HE260A is discharging too much water

these are flow thru models and a lot of water passes thru them. The instructions say to not limit the water by closing valve at all!

Too much water running through to humidifier

With the Honeywell he220, you will use alot of water, trying to turn down the water will only reduce your amount of humidity in the home, you may be able to adjust it a little but you need to take the cover off and reduce the water flow a little at a time watching the water as it flows across the pad, you just have to make sure the humidifier pad is getting plenty of water across it, to little and you lose your humidification, hope that was helpful to ya, thanks for your question,

Humidifier not working

Depending on the age, transformers do go bad. It will have a odor to it if it is burned out, I just checked and the doorbell transformer at home depot is sufficient to run the humidifer. Dont worry that it is 20VA instead of 10VA. The VA is just the load it can handle, the higher the number, the higher the load. The transformer at home depot is around $15 dollars. You will use the 2 outer of the 3 screw terminals for the low voltage. I hope the helps. Steve

Install HE220 HoneyWell , humidity not increasing in the house.

You can try installing the water line to your hot water if it is installed on cold line for more humidification. You should make sure your humidistat is up line 6" @least from humidifier for proper humidification measurement.
