Is my humidifier working?

Thursday, November 24, 2011 by Aprilaire Team
Consumer question:

I am not sure my humidifier is working correctly anymore. When the furnace is running, I can force water over the panel by using the Test setting, however, even at the highest setting (7), The humidifier will not 'click' on and start running water. The humidity level in my house is 41% according to a separate Thermometer/hydrometer. The outside temp has been anywhere from 10 up to 40. Last year, I could easily get (Too much) condensation on windows, if I turned up the setting to a high level. Now we are receiving static shocks in our house, and dry nose/skin issues. Any ideas?

Aprilaires' response:

Thank you for contacting us. The humidity controller does have a maximum setting of 45% (+/- 2%) so it is conceivable that the humidity level could still be too high for it to come on outside of test mode consistently, even though a lot of your observational information would indicate a lack of humidity. If your humidify gauge is continually registering low reading (30-35%) and the humidifer is still not coming on, with the furnace running, there may be a control issue.
