Why is My Vape Pen Blinking? 8 Quick-fire Reasons & Fixes

I’m sure you’ve been there—sitting outside at the end of a long day, your lungs itching for that first hit of smooth, sweet vapor and then, a blinking light. You press the fire button and yet, nothing.

As a vaper, there are few things as frustrating as being robbed of your well-deserved vape session, or as demotivating as being denied those cool, delicious clouds when you finally get a chance to kick back.

In this article, we’ll be going through eight possible reasons your vape pen may be blinking and, hopefully, how to fix them to help you get back to pumping clouds and chasing flavor.

What is the LED Light for?

You may want to know that the LED light behind your vape’s fire button is used by most manufacturers to give you any warnings or signals that could interfere with your vaping experience, especially if the device doesn’t have a digital display.

While the meaning of these warnings can vary according to manufacturer or device, there are a few possible causes that are common among vape pens.

8 Reasons Why Vape Pens Blink

1. Low or Dying Battery

The most common reason for a flashing light on your vape pen is to indicate that your battery is running low.  When there is not enough power coming from the battery, your vape will give a blinking light (a red light with some devices) to let you know it needs to be charged. 

To see if this is the case, charge your vape until the light stays on (or stays green), indicating a full battery.

2. Fire Button Locked

Some devices on the market allow you to lock the fire button to prevent your vape from accidentally firing while it’s in your pocket or bag.

To test if this may be the issue with your vape, press the fire button three times in quick succession, then give it another go. Some vapes require you to press it five times to unlock it. 

Take a look at your manual to see if your vape has a lock function and how you can deactivate it.

3. Tank too Tight, or too Loose

The connection between your battery mod and tank can sometimes be a little bit tricky. If your tank has been screwed on too tightly or not tightly enough, it won’t make a connection and will give you a warning, usually in the form of a flashing light.

Try screwing your tank on firmly then gradually loosening it bit by bit. Between each turn, test the fire button to see if your device fires.

4. Proper Cleaning and Assembly

In some cases, the only issue is that your vape needs a quick clean and re-assembling. If any liquid has gotten on the connectors, or any of the threading is skew, it might be stopping your device from making a proper connection. 

With clean hands and on a clean surface, try taking apart the various parts of your vape and wiping them with a dry cloth or tissue. Then, reassemble it and try to have a hit.

5. Fire Button Stuck

Unfortunately, like most electronics, vape devices do have some weaker components, mainly, the firing button. Because of general wear and tear or because some liquid leaked underneath, your fire button may become stuck. 

If this is the case, your best bet would be to take it to your local vape shop and let them have a look at it, although it may be time to consider a new device.

6. Coil Shorting

If you’re building your own coils, or even if you’re buying stock coils, there’s a chance that they are causing a short in your device.

If the resistance is too low or the coil has been damaged, it will immediately send an error message to your device which then flashes the warning to you. Try rebuilding your coils or returning the faulty stock coil to see if this fixes your problem.

7. 510 Pin Dropped

If at any point your vape has been dropped, the impact may have dislodged some of the smaller components inside your device. The more common of these is the connection between the battery mod and the tank: the 510 pin.  

If the 510 pin has dropped or become stuck in the ‘On’ position, your vape won’t fire and will most likely give you a flashing light. If the staff at your local vape shop don’t do repairs, it might be time for a new mod.

8. Safety Features

Finally, vape pens these days come equipped with an array of safety features. That means your vape pen may be blinking to indicate a specific warning.

Signals like these are in place to let you know of any shorts, battery faults, or damage that your device may have. Take a look at your manual or ask the staff at your local vape shop to see what safety features your device has and what the warnings could mean.

Wrap Up

Well, there you go—the eight possible reasons why your vape could be blinking. Of course, these are not all the causes, but these are some of the most common among vaping devices.  

If you’re ever in doubt, the user manual will give you tips and info for your specific device which can help you troubleshoot it more accurately. 

Further, the staff at your local vape shop are experienced vapers who will have you up and going again in no time. Don’t hesitate to give them a visit and ask for some help.
