Troubleshooting Problems With an Aprilaire Humidifier

Adjust your Aprilaire humidifier as necessary with the control panel either installed in the cold air return duct or on one of your home's interior walls.The water panel is the backbone of the Aprilaire humidifier system and must be cared for properly for the best performance. Also perform annual and periodic preventative maintenance such as changing the water panel, flushing the lines and inspecting the unit for cracks or signs of wear to prevent most problems. Contact your dealer or heating contractor for issues you can't resolve on your own.
