My humidifier keeps running unless I turn down the humidistat? Is that correct?

Consumer question:

Today I set the humidity control just to make sure the unit was ready for winter and once the furnace turned off the fan on the humidifier continued to run, as well as water. When I took the cover off this fall to replace the panel I didn\'t notice anything unusual, but now it just continuously runs unless I turn the humidity control knob below the house ambient humidity.

Aprilaires' response:

If the unit is shutting off when you set the humidity level below the current level of humidity that is consistent with normal operation. With running constantly there could be a couple of issues. The unit could be undersized for the desired humidity level, It could be a wiring issue with the control. Or there could be an issue with the relative humidity sensor. I would recommend turning it up to the minium setting where the unit comes on and then see if the unit shuts off after running for a time. If it does it should be functioning correctly, if it does not. I would call for service.
