Honeywell humidifier HE260A solenoid valve
Hello:
The solenoid (32001639-002) on my 1-year old Honeywell Humidifier HE260A appears to be malfunctioning. I can hear something clicking when I turn the humidity control ON, even the valve is hot on the outside when is ON. However, it doesn't seem to allow water to flow from the inlet side (saddle valve works with no problems) to the outlet side (feed to the pad).
Can I disassemble it and clean it somehow, or should I just spend at least $60 and buy a new one for a brand new humidifier?
Thank you in advance,
John

Is the water valve turned on?
Undo the water line fitting at the solenoid valve, to maek sure the water is going to it. if you do have water going to it, then look inside, you will see a screen inside, remove and clean if needed.

Also, I am not sure of the whole wiring setup even though it worked last year. I have the following:
From 24V transformer side (pin 1), hot wire (red) goes to one solenoid wire. its white goes to the other solenoid wire but is not connected on the transformer side.
From same 24V transformer (pin 2), a second wire (red) goes to ON of humidistat. its white from the transformer side is jumpered together with the white from pin 1.
A third wire (red) goes from C of humidistat (H8908B1002) to Norm Open of the sensing relay. Its white from the humidistat side is jumpered together with the white from the ON side. The other side of the white (C) ends up in Common of the sensing relay.
Any ideas??
Thanks again.

I am sorry, didn't meant to confuse you. 
you r right though, a drawing or a pic would have been better.
the good news is that I managed to fix it by replacing the humidistat, there was nothing wrong with the solenoid valve. Hopefully I wont have to do it again next year.
thanks

new problem - water runs constantly
Hi,
Unfortunately I am reopening this, because I found out this morning that I have the same problem as Lefty9425, i.e. water runs constantly thru the humidifer, even though the furnace is off.
So I am attaching a drawing of the wiring, any help will be much appreciated. thank you.

Thanks for the drawing! Sure made it a whole lot easier. It's wired right.
Unhook one of the wire off the sail switch and see if it stops.
If it stops, then the sail behind the ductwork may be stuck.

thank you for the reply. I have done that while the furnace was running, and it stopped the water flow. I am not sure what else I can do besides checking the sail (as you suggested). Will the replacement of the sail switch with an A50 relay be an alternative?
thanks again.
thanks again.

It's an American Standard Trane #TWV036B140A1.
I also noticed that when the furnance turns off, the sail remains on a horizontal position instead of a vertical one (which is off I think).

You got an Air Handler there, not a furnace.. So I am guessing you have heat pump?
There is no port on the board to wire the humidifier to it. A sail switch or A50 relay is needed..
I've never been around a sail switch, I am guessing there is a spring that bring the sail back up, or the sail is dirty with dust build up, the weight of the dust is keeping it down?

yes, there is a spring that is supposed to release the sail back up when the heat is off, that doesn't happen. The sail stays on the ON (horizontal) position...therefore water flow all the time.
I am going to replace the sail switch with an A50 relay...have already ordered one. Will the position and wiring be similar??
thank you again.

Hi,
I am not sure how to install and wire the A50 relay.
Do I connect the 2 wires of the relay to the C and ON of the humidistat? Also I am not sure where exactly goes. Can I just put it where the sail switch is at now?
thank you again.

You have to put the A50 on the wire that goes to the blower motor. You need to look at the board to see what color wire is hooked on HEAT tap.
The wires that was on the sail switch needs to be moved into the blower area where the A50.. Wire the A50 as the same as the sail was wired up.

A final update on this. The relay didn't work with the current blower...dont know why. However, the sail switch is working now; it was placed too close to the edge (Beware) and everytime the heat turned off, the sail was stuck at the horizontal position. 
thank you Jay!
