My humidifier is very chatty well really just chatering.

Consumer question:

My 700M makes a chatering noise when the humidity control is moved and when the humidity changes. I think it is coming from the water selenoid, but I can not be sure.

Aprilaires’ response:

Thank you for contacting us. The problem that you are experiencing has occurred with other customers that were having issues in getting the proper power to the humidifier to allow the humidifier turn on. Basically what is happening is that the solenoid is not getting the full 24 volts and 10 volt amps required to open properly. Depending on which generation of 700 humidifier you have and what is wired to the humidifier between the humidistat and humidifier would determine what the correct trouble shooting step that I would suggest at this point. If you could advise the color of the unit and what is wired between the humidistat and humidifier, I would then be able to give you a better direction in trouble shooting the humidifier. This may be easier if you called us with your response at 800-334-6011. You may still need to have an installing contractor to trouble shoot the humidifier further. I look forward to your response. If you have any other questions please contact us at 800-334-6011.
