Welcome to our Humidifier Parts Page!
Problems we see ever now and then with humidifiers where the water will not flow, or the water will not stop running, even when the humidifier is turned off. In many cases it could be a bad water solenoid valve. Check the following before condemning the water solenoid valve.
Make sure the water saddle valve is not restricted by turning the saddle valve on. Loosen the compression nut slightly where the 1/4" copper tubing enters the saddle valve. If water comes out then your saddle valve is not clogged, and is OK. If there is no water coming out then you will need to replace your saddle valve.
Take the compression nut loose on the end of the solenoid valve that exits up to the water distribution tray (not the end where the water supply copper tube enters). After you take the tube off you should see a tiny plastic orifice up inside the tubing. Lots of time I see the orifice stopped up with hard water deposits. The orifices are sold below. This will definitely cause the water to not flow in your humidifier. You can take a thin needle and reopen the hole or purchase another orifice to eliminate this problem.
If you water flow continuously and will not shut off when the blower stops you probably need a new water solenoid valve. You can check to see if it is the solenoid valve or an electrical malfunction problem by turning your furnace power off or unplug your humidifier. If the water continues to flow with the power off then you definitely need one of the valves
