Honeywell Humidifiers - Answered Questions & Fixed Issues

solonoid valve not shutting off on water line .

Question edited for clarity, hemostat to humidistat. A hemostat (also called a hemostatic clamp, arterial forceps, or pean after Jules-?mile P?an) is a surgical tool used in many surgical procedures to control bleeding. (Hemo - Blood) For that you will need dealer service. The only thing you can try is a Power Reset. Turn off the power to it by removing the power lead for at least two hours to reset the control board. https://www.google.com/search?q=Honeywell+Trueease+HE+250a-1005+short+cycling ..

It sounds like the wiring for the humidifier may not be correct. The solenoid valve, which controls the flow of water to the humidifier, should be wired to the humidistat and the transformer, not to the furnace or fan. It is possible that the bottom wire of the solenoid is connected to the wrong terminal on the transformer or humidistat, or that the top wire is connected to the wrong terminal on the humidistat. I recommend consulting the installation instructions for your specific humidifier model, or consulting a professional HVAC technician to verify the correct wiring.

The drive belt is broken then and it needs to be replaced.

Sounds like the high pitched noise is coming from the solenoid valve which allows water to enter the humidifier. Typically when the water pressure is too high, it causes this high pitched sound at the solenoid valve. You can adjust the water pressure a little at a time and see if it helps, just make sure you’re getting enough water across the water panel.

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,

You may be able to get a schematic from Honeywell that shows the connection points.

Malfunctioning, defective or both

The replacement solenoid may have been defective.

The obvious solution is to replace the humidifier that became defective while in storage.

What you can do is try and clean the contacts. Open the door on the thermistat and remove the two screws, after that you can seperate the part that is mounted to the wall and the front panel. Look at the part that is mounted on the wall and you'll see the contacts that should be a copper color. They might be black from age. Clean them and you'll be surprised how well it will work after that.

Very first thing. If it won’t turn on, unplug it, and check the cord....especially if you have, or have had, a rabbit that has already chewed through every other wired devices you have ie: TV, satellite dishes, DVD players, other electrical cords.
I got my humidifier year before last and only used it a few times that year. Our humidity was fine until now, so the humidifier was still new as far as I was concerned. I checked every online help suggestion before I remembered Buster. Sure enough....exposed and partially chew wiring. I thanked God that I hadn’t been shocked.
Thank you, Daddy, for teaching this 70 year old grandma how to splice wiring and install other electrical wiring when I was a teenager. I miss you so much.
CAUTION: UNLESS YOU KNOW EXACTLY HOW TO SPLICE WIRING DON’T THINK YOU CAN FIGURE IT OUT. TAKE YOUR APPLIANCE TO A SPECIALIST TO GET A BRAND NEW WIRE PLACED ON YOUR APPLIANCE. I CANNOT EMPHASIZE THIS ENOUGH. IN FACT, TAKE IT TO AN ELECTRICIAN ANYWAY.

Needs to be wired to work on the blower circuit. You must be drawing power from a source that is always on

That means it is time to replace the UV bulb.

yes water should turn off solinoid is bad

thanks for you question,
the residue that you are seeing is Calcium, it is a natural mineral that is found in all water, the easiest way to remove the calcium build up from your humidifier screen is to use (CLR) it is a calcium, lime and rust remover, a simple diluted mixture with water, then soak the screen for about half an hour, rinse the screen then reinstall, a soft water system would help with the calcium build up as well, but tend to be alittle on the spendy side, your could try inline mineral filters that need replacing yearly, I really hope that helped ansewr your question, let us know with some feed back, thanks again for your question, mr.grzz

Bypass Humidifier HE225 265 Check the manual and the support options. This is a water valve that is not sealing

get a better brand as 2 failures of the same brand indicate design faults report the matter to the manufacturers engineering department and ask questions as to why the failures occur

There is normally a capacitor to prevent surges across the motor it might the short circuit.# and preventing the motor from starting.
