The airflow sensor malfunctioned and activated on its own, too much e-liquid on the coil, and a dirty or clogged coil are the main reasons why the IGET Bar light stays on and makes a sound.
Please fix it by blowing hard on the mouthpiece of the IGET Bar puffs and then use a clean cotton swab or paper towel to clean the coil of dirt and clogs.
If the above methods do not work, please contact the Vape IGET you purchased for advice or replacement.
