How to Identify If Your Vape Coil Has Expired

If you’ve been using your vape device for a while and notice that the flavor or performance isn’t quite the same, it might be time to take a closer look at your coil. In this guide, we’ll walk you through how to identify if your vape coil has expired and what signs indicate it’s time for a replacement.

1. Burnt Taste

One of the clearest signs your coil is burnt out is a strong burnt taste when you inhale. This usually happens when the cotton inside the coil isn’t properly saturated with e-liquid or has been burnt over time. If that burnt flavor lingers even after refilling the tank or letting the device rest, your coil is probably done for.

2. Bubbling or Gurgling Sounds

Hearing strange bubbling or crackling sounds while vaping? This could mean your coil is flooded with too much e-liquid or there’s leakage into the coil area. If the noise keeps coming back and cleaning doesn’t help, it’s best to swap in a new coil.

3. Weak or Dull Flavour

If your e-liquid doesn’t taste as rich or flavorful as it used to, your coil might be reaching the end of its life. A fresh coil delivers clear, satisfying flavor, but a worn-out coil dulls the taste and makes the vape experience less enjoyable.

4. Little or No Vapour

Noticing less vapor than usual, or barely any at all? That’s a red flag. When a coil gets old, it loses its ability to heat the e-liquid properly, resulting in poor vapor production. This is especially obvious after taking several pulls with almost no cloud output.

5. Leaking from the Device

Unexpected leaking from areas that were previously dry often points to a damaged or incompatible coil. A faulty coil might fail to vaporize the e-liquid properly, causing overflow or leakage. If your tank is okay, check your coil.

6. E-Liquid Turning Dark

If your e-liquid turns dark or brown even shortly after refilling, it’s a sign your coil might be burnt or too old. Burnt materials inside the coil can contaminate your juice, affecting both color and flavor.

Conclusion

Knowing how to identify if your vape coil has expired can save your device from damage and give you a much smoother vaping experience. Look out for signs like burnt flavor, reduced vapor, or darkened e-liquid — and don’t hesitate to replace your coil if needed.

Frequently Asked Questions (FAQ)

1. How often should I replace my vape coil?
   It depends on how much you vape, but typically every 1 to 3 weeks. If you vape frequently or use sweet e-liquids, you may need to replace it more often.
2. Can using a bad coil damage my device?
   Yes. Continuing to vape with a burnt or faulty coil can lead to leaking, reduced performance, or even damage to your tank or atomizer.
3. Why is my e-liquid turning dark even after I just refilled it?
   Darkening usually indicates a burnt or worn-out coil. Burnt particles can mix with the juice, changing its color and taste.
4. How can I tell if the burnt taste is from the coil or the e-liquid itself?
   If you change the e-liquid and still taste something burnt, it’s most likely the coil. But if it only happens with one specific flavor, it might be the e-liquid’s formulation.
