I have an Aprilaire 700 home humidifier that is about 18 months old. It worked fine and I've kept it maintained by changing filters when it was indicated.
My problem now is that it appears to not work properly in that there is a constant cellenoid clicking noise. The indicator lights do not show any error code... the light is green. I've read the troubleshooting guide and don't see this categorie at all. I've done the test/reset steps several times with no changes.
Anyway, the control panel cellenoid constantly clicks and the unit is not humidifying. Any ideas?
