How do you change humidifier solenoid valve?

To change a humidifier solenoid valve, first, turn off the power to the humidifier and shut off the water supply. Disconnect the water line from the old solenoid valve and remove any screws or clips holding it in place. Install the new solenoid valve by securing it with screws, reconnecting the water line, and ensuring all connections are tight. Finally, restore the water supply and power, then test the humidifier to ensure it's functioning properly.
