Need 24v solenoid valve for my Carrier humidifier

Hello, does anyone recommend a good website where I can get a 24v solenoid valve for my Carrier humidifier? I checked and I do have 24v going to the valve but it seems when the furnace blower kicks on, nothing happens. I assume it's the valve.. Worked great last year :-) Interesting how these valves just stop working.?.?

Here is the data:
Valve - A2012-S118
Humidifier - HUMMCCLBP2417-A
