I has the same problem with my HE360 unit. The unit was in fact miswired. The head unit red wires were connected directly to the blue solenoid wires, and activated the solenoid without any signal from the humidistat. As soon as the unit is plugged inn, the water starts running without any signal to the unit. If your unit is miswired, the soleniod blue wires need to be cut and connected to the red crimp connectors.

I had the same problem with my Honeywell HE 265. I ordered part number 32001639-002 from simplyplumbing.com and fixed it today. The solenoid is the same for the HE 220. You'll need a torx screwdriver and a 5/8" wrench. Doesn't matter how you re-attach the electricals, they're DC.

No turn the furnace switch off (the light switch near furnace, if water continues replace solenoid valve. Afterward you adjust to a slow trickle when calling for humidity, anymore is wasted water.

Why does it make a constant hissing sound?


The fill valve inside the humidifier is leaking. This is a common failure as the valve clogs with mineral content from the water.

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.

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 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

I have a whole house Honeywell E365 humidifier which is constantly flowing water to the pad, even when the heat is not on. What could be the cause ?


Hello, the most common reason this happens is because the solenoid valve is bad and remains open allowing water to flow continously regardless if the furnace is on or off. I assume you have either a sail switch or current sensing relay energizing the humidifier when the heat is on, if not thats another reason it would run continously.

Water constantly runs when furnace is on or off. I wired it exactly how the diagram said but the water never shuts off.


Hello, In order for the humidifier to turn on and off you need either a sail switch or current sensing relay. A sail switch senses air flow and will turn on the humidifier when the blower motor kicks on and a current sensing relay senses current through the blower motors common wire. If you have either of theses hooked up already and the solenoid valve remains open then the solenoid valve must be replaced.
