Solenoid Valve for Humidifier system

[Miketv84]

I have a humidifier that is installed on my boiler. Hasn't been working. I tested the voltage from the thermostat and its recieving 24v. Trying to locate a replacement solenoid. Can't seem to find anywhere except 1 on ebay. Did it get superseded by another part number ?

That may be a better question for the manufacture directly.

I would get the Robertshaw one via Ebay.

Before swapping the solenoid, however check to make sure there is really ~24 vac across the leads on the solenoid. If you have an external transformer (I do) the problem could be the transformer, an open wire, or the contacts on the control board are not closing the path.

Free advice: buy some extra input strainers (model 4004 I think), they tend to clog easily.

In fact, you might want to check the strainer in your solenoid valve before you replace the valve, just to be sure the strainer isn't clogged. The strainer is located in the input (right) side of the valve. You'll need a spring hook or something similar to pull it out.
