Why Is My Vape Flashing and Not Working? Common Issues and Fixes

Posted by Anastasia on Jan 2nd 2024

Vaping has gained immense popularity as a healthier alternative to traditional smoking, offering an array of flavors, reduced harmful chemicals, and potential long-term cost savings. However, like any electronic device, vapes can encounter issues, and one frustrating problem many vapers face is when their vape pen starts flashing and refuses to work. If you're in this perplexing situation, fear not! In this comprehensive guide, we'll explore the potential causes behind your vape pen flashing and not working, providing practical solutions to reignite your vaping experience. So, why is my vape flashing and not working? Let's dive in and find out.

Possible Causes of Your Vape Pen Blinking

1. Low Battery

A common reason for your vape pen flashing and not working is a low battery. Typically, the device will flash when the battery level is near critical. This is a built-in safety feature to prevent you from using the vape when it doesn't have enough power.


To resolve this issue, simply charge your vape pen. Plug it into a compatible charger and allow it to charge fully. Most vape pens have a light indicator that changes color to show the charging progress, usually turning green when fully charged.

2. Connection Issues

Battery and cartridge or atomizer connections can sometimes be the source of the problem. If there's a loose connection or dirt and debris blocking the connection points, your vape pen may not function correctly.


Carefully inspect the connections and clean them if necessary. Gently wipe the battery and the cartridge/atomizer threads with a cotton swab or tissue. Ensure that everything is snugly connected.

3. Dirty Battery

Continuing from the previous point, a dirty battery can lead to connection issues and cause your vape pen to flash. Dust, residue, or e-liquid buildup on the battery terminals can interfere with its performance.


Keep your vape pen clean. Regularly wipe down the battery and connections to prevent dirt and residue from accumulating. You can ensure your device works smoothly by performing this simple maintenance.

4. Battery Overheating

Overheating can trigger your vape pen to flash and shut down to prevent any potential safety hazards. Excessive use or chain vaping can cause the battery to overheat.


Put your vape pen in the freezer for a few minutes. Give it some time to rest, and ensure you don't chain vape for extended periods. Additionally, ensure you use the correct wattage settings for your coil to avoid excessive heat.

5. Overuse of Vape Pen

Vape pens, like all electronic devices, have limitations. If you've been using your vape pen excessively, it might be reaching the end of its lifespan, leading to issues like flashing lights.


Unfortunately, if your vape pen has reached the end of its life cycle, it's time to consider getting a replacement. Regularly upgrading your vape pen can help you avoid such problems.

6. Low E-Liquid Levels

Running your vape pen with very low e-liquid levels can cause it to flash. Vapes need a sufficient amount of e-liquid to create vapor, and when the levels are too low, the device may not function correctly.


Refill your e-liquid tank to an appropriate level. Make it a habit to check your e-liquid levels regularly to avoid running into this issue.

7. Burnt Coil

A burnt coil can also be a culprit behind your vape pen flashing. When the coil inside your atomizer gets burnt, it can't produce vapor effectively, leading to issues with your device.


Your atomizer's coil needs to be replaced. Ensure proper coil replacement and priming by following the manufacturer's instructions.

Why Is Your Brand New Vape Pen Blinking?

Sometimes, you might encounter issues with a brand-new vape pen. This can be frustrating, but there are solutions to get it working correctly.

8. Battery Issues

Even new vape pens can have battery problems. If you've just purchased a vape pen and it's flashing, it could be due to a faulty battery.


Talk to the vape pen manufacturer or retailer. A representative may be able to supply you with a replacement or provide you with advice on how to resolve the problem.

9. Locked Device

Certain vape pens have safety features that can lock the device to prevent accidental firing. If your brand-new vape pen is flashing, it might be closed.


Check the user manual for your vape pen to learn how to unlock it. Pressing specific buttons usually involves this process.

10. Factory Malfunction

In rare cases, a brand-new vape pen may have a factory defect that causes it to flash and not work as intended.


Contact the manufacturer or retailer immediately. They should be able to assist you with a replacement or refund.

Why Is My Disposable Vape Blinking?

Disposable vapes are convenient, but they can also experience issues. Here's what you can do if the light on your disposable vape blinks.

How to Fix a Blinking Disposable Vape

Disposable vapes are designed for single use, so there's not much you can do to fix them once they start flashing. However, you can try the following steps:

  1. Check the Battery: If your disposable vape has a removable battery, ensure it's properly connected. Sometimes, a loose connection can cause flashing.
  2. Inspect the E-Liquid Levels: Make sure the disposable vape has enough e-liquid left. If it's empty, that's likely the cause of the flashing.
  3. Clean the Contacts: If possible, gently clean the battery contacts with a cotton swab or tissue to remove dirt or residue.
  4. Contact the Manufacturer: The manufacturer or retailer where you purchased the disposable vape should be contacted if none of the above steps work. They may offer a replacement or refund.

Vape pens may have LED lights that blink different colors to convey various messages or issues. Here's what different LED colors may signify:

Why is my vape pen blinking red?

  • Low Battery: Low battery is often indicated by a red blink. Depending on your vape pen, charging it may resolve this issue.

What does it mean when a disposable vape blinks blue?

  • Bluetooth Mode: In some advanced vape pens, a blue blink signifies that the device is in Bluetooth pairing mode. You can find instructions on pairing in your user manual.

Vape Pen Blinking GREEN

  • Full Battery: When your battery is green, it means that it has been charged fully.

What do the solid LED colors on a vape pen mean?

Apart from blinking, solid LED colors on a vape pen can also convey important information. Let's explore their meanings:

Solid Red LED Light

  • Battery Charging: A solid red light indicates that your vape pen is currently charging. A fully charged battery will turn green once it turns green.

Solid Blue LED Light

Why won't my vape pen hit?

If your vape pen isn't producing vapor when you try to take a puff, there are a few potential reasons for this issue:

The battery is off:

Check if the battery is turned off. Some vape pens have a manual on/off switch or require multiple button presses to activate.

Firing pin sitting too low:

If the firing pin (the small metal part that makes contact with the coil) is sitting too low, it may not make proper contact with the coil, preventing it from heating up. Gently adjust the firing pin to ensure it's in the correct position.

Flooded coil and atomizer:

A flooded coil and atomizer can also prevent your vape pen from hitting. This occurs when too much e-liquid enters the coil, preventing it from vaporizing effectively. To fix this, remove the atomizer or cartridge, clean it, and ensure it's not overfilled.

What is the best way to charge a vape pen battery?

For a vape pen battery to last as long as possible, it must be charged properly. Best practices include:

  1. Use the Right Charger: Whenever you are using your vape pen, it is essential that you use the charger that came with it or one that is compatible with it from a reputable brand. When batteries are charged incorrectly, they can be damaged.
  2. Charge on a Stable Surface: Place your vape pen on a stable, non-flammable surface while charging. Avoid charging it on your bed or sofa, which can pose a fire hazard.
  3. Don't Overcharge: Make sure your vape pen does not remain fully charged for an extended period of time. The battery can be degraded over time by overcharging.
  4. Never Ignore any Blinking Lights: If your vape pen has LED indicators that blink during charging, pay attention to them. Different patterns may indicate charging status or issues with the charging process.
  5. Unplug After Charging: To avoid overcharging or damage to your battery, unplug your vape pen after it has been fully charged.
