Humidifiers and Dehumidifiers - Clean or replace humidifier soleniod valve

After purchasing our first home this summer we purchased a new evaporative pad for the General Aire 1042 humidifier that is installed on the return of the furnace. When the humidistat is turned up the soleniod clicks however no water passes through to the pad. The valve to this water line is open and water will flow to the soleniod however it will not go beyond this. Can a solenoid be cleaned, and if so how? Or must a new one be purchased?

Try cleaning it out.
Turn off the water, and undo the water line from the valve..

Remove the brass strainer body from the valve.

Remove the strainer with care from the fitting.

Clean the parts and of the small orifice is plugged, unplug it with a small needle.

I disassembled everything, cleaned the in line filter w/ vinegar and used a safety pin and vinegar to clean the solenoid valve assembly. After reassembling everything water still will not pass through. It will continue to make a single click when the humidistat is raised when the blower is operating.

Any other suggestions would be appreciated. Thank you for trying to help thus far.

Do you have a meter? Take a meter and check for voltage at the valve on call of humidity. It should read around 24 volts.

If you got voltage, and know for a fact that the water does flow up to the valve, then guess time to replace the valve.
