Struggling with your Njoy e-cigarette? Common issues often stem from simple fixes. Follow these quick troubleshooting tips to resolve common problems efficiently.
Device Not Heating or Producing Vapor
If vapor production is weak or nonexistent, focus on key components:

- Charge the battery fully using an approved charger; wait for the LED indicator to confirm completion.
- Clean the atomizer if clogged—gently wipe with a dry cloth to remove residue.
- Ensure all connections are tight between the battery and cartridge; re-seat them firmly.
Battery Not Charging or Powering On
A dead battery is a frequent culprit:
- Inspect the charger and port for dust or damage; clean lightly with a cotton swab if needed.
- Test with a different charger or power source to rule out faults.
- Reset the device by pressing the power button five times consecutively for hard resets.
Poor Flavor or Leakage Issues
Unpleasant taste or leaks can ruin your experience:
- Replace the cartridge if old or expired; store extras in cool, dry conditions.
- Check for cracks or loose seals in the cartridge; swap if damaged to prevent leaks.
- Clean the mouthpiece regularly with a soft, damp cloth to maintain airflow.
General Maintenance Tips
Prevent future problems with routine care:
- Store upright in a temperature-controlled environment to avoid condensation.
- Wipe components weekly with alcohol-free wipes to prevent buildup.
- Avoid overcharging to extend battery life; disconnect once fully charged.
If issues persist, refer to your user manual or contact Njoy support for model-specific guidance.
