Solenoid not working on a humidifier He225a - Honeywell HE365 Humidifier

Hello, if there is water to the solenoid valve but not passing through it than the solenoid valve is malfunctioning and must be replaced. However, if there is no water at the solenoid valve then either the saddle valve or supply line is clogged with sediment. A easy way to chek the solenoid valve is apply power directy to the solenoid valve from the transformer, if it does not open then replace it.

Make sure the new pad you installed is in the right position. The pad is marked with a black dot about the size of a quarter. This end should be up for proper water flow through the pad.I fwater flow is being restricted at the pad the vibrating nosie that you are hearing is the dry portion of the pad vibrating agaist the platic housing of the humidifier. This noise stops once the pad has absorb enough water in this area of the pad.

Hello, You can tell if the humidifier is working if you see water flowing into the drain line. Also , when the furnace turns on you should here a click at the solenoid valve on the humidifier, this means that the solenoid is open and letting water into the humidifier.

the solenoid allows water to flow to jet that then runs down the pad the solenoid is control by the stat

Put the humidifier number, not the solenoid number, into Google or directly at www.appliancefactoryparts.com . They show a breakdown of the humidifier and let you order replacement parts. I've just ordered the solenoid assembly, which they say is in stock.

This posted question is exactly one year old, but I just got this solenoid valve assy from ontimemall in Phoenix AZ. I don't have the receipt right here, but it was about $90. It is classified as: honeywell 32001639-002 solenoid valve.

HI check there is power there or at the transformer

I am guessing you have sent 24 volts to the solenoid directly and the the solenoid did not activate?

If you have not send power directly

If the solenoid does not activate that way more then likely needs a new solenoid.

Sounds like you may have put 120v through a 24v solenoid and humidistat.
Is the HUM terminal on the furnace 120v or 24v?
If it is a 120v terminal you will need a 120x24v transformer and a new solenoid and maybe a new humidistat.
