5 Causes of a Vape Auto-Firing
- Stuck draw sensor. The airflow sensor may be jammed. Fix: tap gently and clear the airflow path.
- Moisture in the sensor. Condensation can trigger firing. Fix: let it dry at room temperature.
- Debris in the airflow. Lint or dust can hold the sensor open. Fix: clear the air intake gently.
- Pressure in a bag. Being squeezed can activate it. Fix: store it loosely and upright.
- Internal fault. A defective device may misfire. Fix: stop using it and dispose responsibly.
Most cases are a stuck sensor or moisture and clear up with a gentle tap and a chance to dry. If a vape keeps auto-firing after that, treat it as a fault and stop using it.
When to Stop Using It
