My Aprilaire Model 760 appears to run properly but doesn't seem to humidfy the house. When set to max humidity on well-below freezing days, there is not a bit of moisture on the windows, which in the past has been our signal that the thing is working. I have monkeyed around and have even repaired some wiring that was damaged. Is it possible that I crossed wires and caused the fan to run BACKWARDS, ruining proper circulation of air through the pad?
