Humidistat

If the blower fan does not work the humidistat might not be working properly. Try turning the humidistat to its highest setting and see if the blower fan starts working. If not, listen for a click inside the humidistat to know whether the contacts are closing. If the humidistat is providing power but the blower fan still does not work, the problem might be the motor itself.
