Why won't my AER Dryer switch off?

The AER Dryer should always be able to switch off. If the unit will not turn off, check to make sure the switch is in the off position and that no debris is interfering with the switch. You may also move the unit into a dark room to see if the unit will shut down. If the unit will still not shut down following these steps, let the unit fully discharge and then contact customer support as soon as possible.
