Why is my vape flashing and not working?

Everyone has been there - you had a long day and you just want to unwind and take a hit from your delicious Fume or Cuvie. You go to hit it and to your surprise - the LED starts blinking and no hit is produced. What could this ever mean? We are here to go over some reasons why your vape could be blinking.

If your device does not have a digital display, the LED is used mostly to show the battery of the device. If your vape is blinking then it most likely means that it is out of battery or there is an issue with the battery.

Although this is the most common issue, there are still some other things which can happen that affect the experience.

1. Low or dying battery

The most common reason as stated above for a vape pen blinking is to indicate that the battery life is about to end or has ended. When there is not enough power coming from the vape pen batter, your vape will give a blinking light (whatever color the LED is) to let you know that you need to charge it or get a new one (if it is a disposable).

To see if this is the case leave your battery charging until the light stays on or turns green indicating a full battery.

You cannot recharge disposable devices such as the fume infinity, cuvie plus, cuvie, etc.

Some pens blink to indicate the amount of battery. For instance a vape pen blinking blue often means you're at medium battery power, or the device is in medium mode power output (varies by manufacturer).

A vape pen blinking green usually indicates that the battery is fully charged or in high mode power output. A blinking green light usually also means that the charging process is complete.

Meanwhile a vape pen blinking red often means that you have low battery and the pen will switch to low power output mode, especially if the vape blinks while you are taking a drag.

A loose battery connection may also cause your vape pen's light to blink, and the device will automatically shut down. 

2. Fire Button Locked

Some devices allow you to lock the hit button in order to prevent the vape from producing vapor while it is in your bag or pocket. 

To test if this is the issue with your vape, press the hit button three times in quick succession, then try another hit. Some vapes require to push it give times to unlock it.

In order to be sure, look at the manual of your vape in order to find the correct control settings. 

3. Tank Too Tight, or Too Loose

The connection between your battery mod and tank or vape cartridge can sometimes be a little tricky. If yoru tank as been screwed on too tightly or not tight enough it will have a poor connection and stop working completely. The same goes for THC cartridges. Try screwing on your tank firmly and gradually loosening it bit by bit, testing the hit button between each turn to see if your pen fires. Sometimes you may need to clean the heating plate in order to make proper contact with the cartridge.

4. Proper Cleaning and Assembly

In some cases as stated above the issue may be that your vape pen needs a quick clean and reassembly. Liquid and dirt usually gets on the connectors and threading and may cause it to skew which causes a connection problem.

With clean hands, try taking apart the various parts of your vape pen and wiping them with a dry cloth or cotton swab. Then reassemble it and make sure everything is firmly connected to try and have a hit. 

You may also check the charging cable and port in order to make sure that there is no dirt on it preventing it from making contact. 

5. Hit Button Stuck

Unfortunately, like most electronics, vape devices have some parts of them which are weak and may break easily. Mainly the firing button. General use or e-liquid leaking underneath may cause the button to become stuck.

If this is the case, your best bet would be to use 99% alcohol to clean the pen and make sure that all debris is cleared. 

6. Coil Shorting

If you're building your own coils or even buying stock ones there's a chance that they are causing a short circuit in your device. If the resistance is too low or you have a damaged coil you'll get an error message in the form of flashing lights. Try a different coil or rebuilding your coil.

7. 510 Pin Dropped

If you dropped your pen, the impact may dislodge some of the smaller components inside of your device. The most common problem is a connection issue between the battery mod and the tank caused by the 510 pin moving out of place. 

If the 510 pin has dropped or become stuck in the on position your vape pen won't fire and the LED lights will most likely flash or blink red. 

8. Safety Features

Some vape pens come witha  variety of safety features. That means your vape pen may blink to indicate a specific warning. 

Signals like these are in place to let you know of any shorts or battery faults that your device may have. Take a look at your manual or ask the shop where you got it about the safety features your device has and what the warnings could mean. 

Wrap Up

In most cases, a blinking light usually just means that your vape pen is out of battery. Consult your manual in order to get the best answer depending on your device. Your manual will also help you with other functions like the voltage setting, switching to dab mode, and the temperature setting. 

Having your disposable vape give up unexpectedly is annoying as it is. But, at Blackout Vapors, we often have users contacting us with the question – why is my Puff Bar blinking? There can be any number of reasons why that’s happening. For starters, know that electronic devices sometimes do that either because of a manufacturing defect. Or, maybe, errors in using them. Of course, the most common reason would be that the battery has died and/or the disposable has run out of e-juice. Here’s some added information you might find interesting.

Why is my vape flashing and not working?

What exactly is the light doing?

Most disposables have an indicator light that tells you that the device is in use. This light could turn red to indicate that the battery is running low on power. Or, it could blink, which is typically another sign that the battery is dying out. Chances are that the disposable does not respond when you inhale or take a hit. Disposables are designed and calibrated so that the battery lasts for a somewhat longer time than the e-juice. So, if you see the disposable Puff Bar blinking, expect that the charge has died out. While you can learn how to recharge a disposable vape, don’t expect any significant results. The disposable is meant to be discarded after a time.

Well, you could get some more use out of it.

If you check the label on the device, it will tell you that the device should last you up to 200 puffs. While that is technically true, how you use the vape can also affect the usage you get out of it. For instance, if you inhale deeply, the coil will remain lighted for a longer time. You’ll consume more power to keep the coil heated. In that case, the battery is likely to die quickly. Taking shorter hits and letting the battery rest in between sessions will make it last longer.

For now, if you notice the Puff Bar blinking, set it aside for a few hours. You might be able to get a few more draws out of it. But, that’s not a given. Getting a new one is a better thing to do.

Shorter sessions allow the wick to absorb e-liquid.

When you take a hit, the coil heats and vaporizes the e-juice. Continuous hits dry out the wick and do not give it enough time to soak up more e-liquid. If your device isn’t blinking but does not release clouds either, you might want to set it aside for a while. Once the cotton or fiber wick hydrates, your pen could start functioning again. Many brands carry a small window on the pen’s side that allows you to monitor the e-juice quantity. Keep an eye on the level, so you know when it’s time to get a new vape pen.

Try shaking out the bubbles in the tank.

Here’s another scenario. You can see that there’s enough e-juice in the tank and the disposable Puff Bar’s blinking or does not deliver clouds. Oftentimes, air bubbles in the tank interfere with e-liquid absorption. If that happens, tap the pen gently on a surface to release the air. Give it another minute and resume vaping.

Improper airflow and sensors can take away from your vaping experience.

If the Hyde Vape does not activate, try blocking the air vents partially or entirely with your finger. For one, you’ll prevent cold air from entering the vape, so it heats up more efficiently and starts functioning. Or, the pressure helps improve airflow and dries up the condensation buildup on the sensor. You might just get the device working again. Also, lookout for a burned taste and smell, which is another indication of the cotton wick being too dry and singeing.

Check if the device starts blinking after some use.

Think back at your vaping session. Did the device start blinking as soon as you took the first draw? Or, was the Puff Bar blinking after a few deep hits? If you’ve been taking long hits, that probably means that the vape is overheating. Set it aside and let it cool before trying again. Moving forward, take shorter hits and breaks in between each session.

Your device circuit might have shorted.

Manufacturers typically add circuit protectors to ensure that the disposable does not short. However, there’s always a possibility of short circuits. If you see the blue light at the bottom continually blinking, it’s best to discard it and get another.

What if a new disposable does not activate?

Although disposable vapes do have quality control measures, there can be instances when a new device does not activate. A faulty assembly could be the cause, and you can try examining the internal setup. Pry open the mouthpiece and check the cotton inside. If the wick is bunched up and blocking the e-juice opening, your vape may not work at all. Use a pair of tweezers to realign the cotton, so it soaks up enough e-liquid.

If the cotton does not seem to be the problem, remove it, and examine the opening in the center. If you spot any blockage, use a toothpick to dislodge it. Replace the cotton and mouthpiece and try again.

How you use the disposable can affect how well it performs.

To get the best functionality out of your vape and prevent running out of battery too soon, remember that the device has a simple circuit without any temperature control. Use it with care using precautions like shorter draws. Too much pressure has another downside. You could suck up the e-liquid instead of clouds. Now that’s an unpleasant experience. Or, the e-juice might start dripping out of the air vents.
