I have a honeywell he220 that worked great last season. This season the water will not run through it. The sail switch seems to be ok.Could it be the solenoid switch? How can I tell?
I have the same problem, humidifier worked fine last season but will not pass water this season.

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.
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.
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 continuouslyuntill 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.
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
I have a HE220, HE 260 humidifier..by 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?
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, mr.grzz
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
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.
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.
