However, much to your dismay, it refuses to work, leaving you frustrated and wondering what could be wrong. While this situation is disheartening, there is a glimmer of hope. In many cases, the user can resolve common technical issues, saving you time and money. 

Whether you’re using a weed pen for dry herb or vape juice, we’ve got you covered. In this article, we’ll explore the reasons behind vape malfunctions. We’ll provide insights on fixing common problems, including those encountered with dab pens. 

Why is My Vape Pen Not Working?

Why is My Vape Pen Not Working

Here are twelve common reasons why your vape pen may not function as expected, along with simple solutions.

Oil Has Settled in the Pen/cartridge

Cannabis oil has a high viscosity. It can become thick and settle on one side of the cartridge. It can impede its smooth operation. To solve this issue, you only need to apply heat to the cartridge. 

Heating it will lower the viscosity of the cannabis oil, making it more fluid and allowing it to flow correctly when you take a pull. So, the next time you encounter this problem, remember that a little heat can go a long way in getting your oil flowing again.

Battery is Not Working

Before troubleshooting any issues with your vape pen battery, it’s important to understand the type of battery your vape uses.

If your vape pen has a pull to draw battery, it remains “on” until it dies, and you can recharge it using the USB port. Pull to draw batteries only need the user to inhale, “puff,” or “draw” in order to function.

Some disposable vape pens have push-button atomizer activation. To turn these pens on, press the battery button five times quickly and hold it down while you take a draw. If you’ve been using your pen’s battery correctly, but it still doesn’t work, look closer at its contact point. 

Check for any damage or residue, such as excess oil. If you notice a clog, gently clean it with rubbing alcohol and allow it to dry completely before reconnecting it to the cartridge.

Dirty Coil

If you’re experiencing issues with your vape battery not working, the culprit might not be the battery itself. Sometimes, the problem could be with the coil, especially if your device has replaceable coils. 

Over time, vape coils tend to burn out, resulting in a flavour and vapour output decline. When you notice these signs, it indicates that it’s time to change the coil. You can locate the coil attached to the device’s atomizer, which is found in the chamber. 

Before replacing the coil, emptying the tank or enclosure is important to prevent any spills. Additionally, remember to turn off the pen to avoid any unexpected shocks.

The Chamber is Too Full

The chamber holds the cannabis material in vape pens. If it’s filled, there’s too much material for the coil to vaporize effectively. It can result in poor vapor quality or cause the vape pen to stop functioning altogether. 

Ensuring the chamber is manageable before attempting to use your vape is crucial. You can optimize the vaping experience by avoiding overfilling. It also helps ensure that your device operates smoothly.

Atomizer is Not Working properly

Atomizer is Not Working properly

The atomizer burns the oil too rapidly, therefore higher settings will cause the wick to burn. Shorten your pull. This will reduce the amount of heat that might end up burning the candle.

3 Common vape pen problems with atomizer are:

  1. Sometimes, accumulated dirt or residue can interfere with the atomizer’s functionality. 
  2. If your atomizer’s coil touches the sides of the tank, it can cause a short circuit.
  3. The chipset, which controls various features of your device, could be malfunctioning.

No Cannabis in the Chamber

The chamber, the part of the vape pen responsible for holding the cannabis material, plays a crucial role in the vaping experience. Without cannabis in the chamber, the coil has nothing to vaporize, rendering the device useless. 

It is vital to ensure that the chamber is filled with cannabis before attempting to use your vape pen. It lets the coil heat the cannabis, transforming it into an inhalable vapour. Neglecting to fill the chamber with cannabis will disappoint you, as there will be no vapour to enjoy.

Vape Flavor Tastes Burnt

This unpleasant burnt flavor occurs when the oil inside the vape cartridge is not settled near the coil. The coil, similar to a candle wick, heats the cannabis oil but can only do so when it comes into contact with the part of the cartridge called the wick. 

So, if your vape tastes burnt, it’s essential to check if the oil has settled to one side of the vape cartridges. In such a case, you can try the hair dryer method. Warm the cartridge with a hair dryer to encourage the cannabis oil to spread. 

It’s essential to store your vape pens upright. It prevents the oil from settling to one side.

Over-tightening the Atomizer

If you tighten it, it can disrupt the connection with the device. Use a paper clip to slowly pry the metal ring up.

If you’ve ruled out over-tightening as the issue, there might be a problem with the center pin, also known as the 510 connectors. This part connects the atomizer to the mod, so you may need to replace it if it’s faulty. 

Liquid is Leaking Into the Mouthpiece

One common cause is over-tightening, which can disrupt the proper seal and lead to leaks. Storing your vape pen on its side or upside down is another factor. It can cause oil to seep into the vaporization chamber. 

It may result in excess oil being drawn into your mouth when you take a pull. When refilling, avoid getting cannabis oil into the central tube, as this can also cause leakage. To prevent this, fill the cartridge at a 45-degree angle and leave a bubble of air at the top to create a vacuum. 

Adjusting the voltage and heat settings to a higher level may help if leakage persists. It allows the atomizer to vaporize more THC oil per pull, preventing the oversaturation of the coil.

Pen/cartridge Mouthpiece Clogged

Vape Pen Cartridge Mouthpiece Clogged

It occurs when the airflow holes on the cartridge get blocked, often due to lint accumulating in pockets. Luckily, there’s a simple solution to unclog the air hole and get your vape pen back to working order. 

All you need is a small pin or an unfolded paperclip, easily found around the house. Gently insert the pin or paperclip into the clogged air hole and carefully maneuver it around to dislodge any obstructions. 

Be cautious not to apply excessive force, as you don’t want to damage the cartridge. Once you’ve cleared the blockage, the airflow should return to normal, allowing you to enjoy a smooth vaping experience.

Burnt Wick

When the coil wick on your vape is drying out, you’ll get a dry hit or a burnt flavor when you hit it. A dry wick causes this burnt flavor.

When the wick is not soak with oil, the atomizer burns it rather than vaporizing it. This issue causes a burnt flavor and, in rare cases, a permanently damaged wick.

Damaged Contact

The contact is the small metal piece that connects the battery to the atomizer or cartridge. When the communication is damaged, it can prevent the battery from properly connecting. It can lead to malfunction or complete failure. 

This problem is often caused by rough handling or frequent drops. You may need to replace the battery or consult a professional to fix a damaged contact. Taking care of your vape pen and being gentle can help prevent such issues.

Temperature is Too Low or Too High

The temperature setting of a vape pen plays a crucial role in the vaporization process. If the temperature is too low, the coil fails to reach the necessary heat to vaporize the cannabis. 

So this can result in subpar vapor quality or render the vape pen completely non-functional. Before using your vape pen, ensure the temperature is adjusted to the recommended setting.

If you don’t want to throw away your disposable vape pen because it doesn’t work, you should invest in a good one. Don’t worry! Here’s a comprehensive buying guide on how to choose the best disposable vape pens.

Vape Pen Troubleshooting Tips

Vape Pen Troubleshooting Tips

Here are seven important tips to fix the vape pen Troubleshooting: 

Check the power switch

Ensure that your vape pen is turned on. Most vape pens require you to press the device’s button five times within two seconds to activate it. The controller will light up, indicating a functioning battery. Some vape pen work by clicking three times.

Adjust the voltage

Incorrect voltage settings can cause performance problems. Verify if your device allows manual voltage adjustments and set it to the appropriate level for your vaping product.

Most THC or CBD carts should be vaped at 3.3 volts or lower, while denser oils or e-juice may require higher settings. As a general rule, it should be turned down to the lowest setting. We think that 2-3.2 volts is a good starting point for THC oil cartridges that you vape.

Unclog the vape cart

If inhaling becomes difficult, clean the mouthpiece with alcohol and cotton swabs. Wipe away residue, and use a safety pin to scrape off stubborn residue if necessary.

For weed pens, apply heat from a hairdryer on its lowest setting to loosen the residue, making it easier to clean. Refer to our guide for unclogging carts if needed.

Check the cart connection point

A common problem with vape pens is that the metal rings that carry electricity get pressed in too far and don’t touch each other. Ensure the vape cart is tightened but not forced. It should be snug and secure with a finger-tight hold.

This can happen if the pen is squeezed too much. Use a paper clip to slowly pry the metal ring up. This is an easy answer. Make sure you don’t lose the ring! Only a very thin wire holds it in place. Only a small amount of even lifting is needed.

Defective Battery Troubleshooting Tips

Defective Battery Troubleshooting Tips

If changing the ring on the cartridge doesn’t fix the problem, try the same thing with the battery. If you see dirt or oil on the outside of your THC cartridge or vape battery, you can try cleaning the connection port with alcohol and a Q-tip. Then, let it dry before trying to recharge again.

Your connection plate may still not be making good contact. To fix this, take a pin and slowly lift up the connection plate on both your THC capsule and battery. The link plate is at the bottom of the cartridge or where the cartridge screws into the battery.

You only need to lift the connection plate very lightly. If you pull too hard, the wires inside the battery could be exposed, which would break it. After carefully adjusting it, connect the battery and start smoking.

Be careful not to use your vape pen too much. If you do, it could start to get very hot, which could damage the battery and burn your oil. After you’ve used the vape pen a few times, give it some time to cool down before you use it again.

Fix a stuck connection pin:

Sometimes the positive connection pin gets pushed down and fails to contact the cart. Use a small screwdriver or knife blade to push it back into place.

Replace the coil:

If the battery isn’t the problem, it could be a burnt-out coil. Look for the coil in the device’s atomizer and replace it. Remember to pre-saturate the new coil with cannabis oil or e-juice to avoid burning.

Try a different charger:

USB chargers are demanding. If your battery isn’t charging even after a couple of hours, consider getting a new charger. Ensure compatibility with your device to avoid any issues.

How to Clean a Atomizer?

Maybe you haven’t cleaned your atomizer in a week or two, and the dirt has solidified, making your vape juice taste like ash. In this case, you require an intensive cleaning.

For a more thorough cleaning, soak your atomizer in isopropyl alcohol for 30-60 minutes. When you wipe clean the atomizer with a damp cloth, the hardened dirt will get soaked and will break down and peel away from the atomizer.

Why is My Vape Lighting Up but Not Hitting?

Your vape may be lighting up but not hitting because bubbles can get trapped in the pre-filled pod or cartridge, causing it to clog and impede airflow.

Why is My Vape Blinking Blue and Not Hitting?

The blue blinking light on your vape indicates a loose battery. It is caused by dust accumulation or excess oil clogging the contact point.

How Do I Fix My Vape Pen From Blinking?

To fix a blinking vape pen, try shorter pulls, hold the device upright for two to three minutes, and absorb excess liquid using a paper towel on the mouthpiece.

Three blinks on a vape pen indicate a short circuit. It triggers the device’s quick circuit protection feature, which renders it inactive.
