Continous ware flow on Honeywell HE220A Humidifier

I have installed the Honeywell HE220A humidifier. When the furnace cuts out the water continues to flow through the drain tube. As far as I can see it's wired correctly, ay least as far as the instructions go. Any help would be appreciated!

    I have the same problem. When I touched the sail switch, it stopped the water flow. I have my sail set for downward airflow. I took out the sail and found that the plastic flap once it's blown down, will not come up to stop the flow. (here's how it works: When the return air blow the SAIL down, the water starts running. When the furnace is off, the fan stops sucking in the cold air and the SAIL flap should go back up, and the SAIL switch will stop the flowing water). I wonder if I have installed the SAIL too low. The instruction said it has to be at least 15 inches below the horizontal duct. I have one round air duct coming in from outside that is lower. So I measure 15 inches from that duct. Therefore my switch is low.



    also, when I take out the SAIL and blow on the plastic hard, it stayed there after I stopped blowing. wonder if I have bad spring or faulty switch.



    please advise. Should I put the Switch for warm air supply? would the plastic flap last? Please someone ..somwhere must have solutions..or advices. Thanks in advance

    I have the same problem and after taking apart the solenoid and noticing a pin hole through the valve body I contacted Honeywell support. Through subsequent emails and phone calls I sent them this picture where the white background shows up as a white dot at the center and bottom of the inlet port. A technician called be back and had me reassemble the valve and put it on humidifier. Everything checked out except water flowed continuously through the valve. He insisted the hole is supposed to be there.



    Although Honeywell support has been polite and responsive I doubt their technical prowess. I'm guessing there was a manufacturing problem where one or both of the ports was drilled too deep. This sort of problem should be fixed free of cost to the consumer.

I am having the same problem. I have had my humidifier for about 5 years now and I just started having the problem where the water continuously flows through the solenoid. I took apart the solenoid by removing the fittings from both sides. When I did that, I noticed that there was a hole in the metal that allowed me to see through to the other side. Apparently, it had corroded and and broken through, allowing the water to pass through the solenoid without really going through the valve within the solenoid. There are several sites that sell replacements for about $70, which is not cheap, but cheaper than buing a new humidifier for $120. Here is one site I found: http://www.iaqsource.com/product.php/honeywell/32001639-002/?product=112783&category=1142

The reason why your SAIL switch stays there after blowing on it is because you have 2 springs attached to the switch. If you read the instructions you need to take off one of the springs (silver color) when your return air is downward and vice versa with the red colored spring. You should only have 1 spring attached after a successful installation.

Is this unit design to have a continous flow into the drain? My flows all of the time.


Hello, the humidifier should only be running when the furnaces blower motor is running, therefore it should only drain when the humidifier is on and not flow continuously. Usually the humidifier will keep draining water when the solenoid is stuck open and should be replaced with a new solenoid valve.

Unless you are using a current sensing relay or sail switch, you need to get the humidifier power from the blower motor supply so it only operates when the blower is on.

Since you can manually control the humidifier, there is not a fault with the solonoid.

I have just completed installing a Honeywell HE220A humidifier to a Carrier Weathermaker 8000vs that was installed in 2003. My problem is that all the identified circuits in previous posts on the circuit...


I believe that Carrier has a 24 volt setup for humidifier but am not sure. On the circuit board I think there is a terminal (HUM). If there is this terminal connect 1 wire to this and 1 wire to C terminal.
If not,pretty sure there is a 120 volt EAC terminal. This would only kick on when blower is on. If you have to use this you would have to install transformer to the EAC connections

Honeywell HE220A water not reaching humidifier


Replace the Valve on the unit. Check the small filter inside of it where the waterline attaches first. If its clear and you have lots of flow from the 1/4" line the replace the valve.

Honeywell he220a install


thanks for your question,
you have to install the bypass humidifier on the supply side of your heating system, (hot side) and run a bypass pipe from the return side, (cold side), it does matter which side it goes on, you do not want water vapor going directly into your furnace, as this can damage it and shorten the life of it, your humidistat is installed on the return side of your duct work, this will allow proper operation of the unit as the humidistat senses the moisture in the air and brings on and shuts down the humidifier as needed. hope that helped to answer your question, please let us know what you think, again thanks, mr.grzz
