Check Your Power Source #
Please double-check to make sure the power cord is plugged into an outlet. If you have an EXO unit, please ensure the batteries have been installed correctly or that they are not low.
Clean Your Diffuser #
Make sure to run isopropyl alcohol every month or the lines will become clogged. It cannot spray as much or as long if the lines are clogged.
Check if Your Running Low on Fragrance #
The unit should maintain at least a 20% level of fragrance for the compressor to pump. If it goes too low you can burn up the compressor.
