MHX3C General Humidifier Humidistat

About the Humidistat

If the humidistat is incorrectly set or isn't working properly, the humidifier won't fill with water. To determine if the humidistat is defective, turn the humidistat to the highest setting and listen for a "click." If you do not hear a click, this indicates that the electrical contacts inside the humidistat are not closing. If you do hear a click, but the humidifier still won't fill with water, it is more likely that another part is defective.
