My Cart Has Airflow But No Smoke? How to Fix

We’ve all been there. Yousit down to vape, take a hit, and nothing happens. You check the battery, it’s charged. You check the cartridge, it’s full. You blow and blow until you realize “Wait a sec.My cart has airflow but has no smoke. What’s going on?” The answer, more likely than not, is that your vape pen is clogged.

Be it a nasty amount of residue or a simple airflow issue, there are a bevy of possible obstructions that canrender your vape pen unusable. Narrowing down the problem can be tricky, but luckily there are a few things you can do to try and clear the blockage and get back to vaping.

Why does your cart have airflow but no smoke?

Any number of things can be preventing you from enjoying a good vape session—and a lot of them have to do with the fact thatvape pens, e-cigarettes, and other vaping devices rely on a delicate balance of liquids and solids to function properly. Upset that balance (as many of us unintentionally do), and you've got a clogged vape pen on your hands.

Clogged vape cartridge

One of the main reasons why your cart has airflow but no smoke is a clogged vape cartridge. Frequent usage tends to lead to the buildup of residue from the vape liquid, especially if there’s no regular cleaning. This accumulated residue can gradually obstruct the airflow, hindering the vape pen's ability to produce vapor effectively. To prevent this, regularly maintain and clean your vape.

Oil type

Who doesn't love takinga hit of CBD or its THC-laden cousin,THC oil? While vaping these oils certainly has its benefits, it can also lead to clogs. Because CBD and THC oils are thick and viscous, they don't always vaporize as cleanly as other liquids.

If you're using one of these oils in your vape pen, it's important to be extra vigilant aboutkeeping things clean. You can also practice storing it in an upright position to help keep the oil from pooling around the mouthpiece.


Pair a sticky oil with a too-hot or too-cold vape environment, and you're practically asking for a clog. Warm weather could cause the oil to become runny, and chilly temperatures could cause it to be thicker. Either way, it'll be more difficult for the oil to vaporize cleanly and is more likely to clog your vape pen.

The biggest way to prevent these kinds of not-so-fun scenarios is to be vigilant about not leaving your vape pen outside in the elements (that includes your car). Store it in a cool, dry location when you're not using it.

Another way to nix any temperature issues in the bud—pun intended—is to "preheat" you vape before you use it. Not every device will allow for this, but some let you warm up the oil by pressing down on the button for a few seconds before you start taking hits. This could help to ensure that your oil is the right consistency when it comes time to vape. 

Flooded chamber

If you've been neglecting your vape pen and letting the cart sit around for too long, it's possible that the liquid has seeped to the bottom, where it oversaturated the wick and completely drowned the coil. The result? You get to enjoy some nice, paper-thin vapor and a slight, burn-flavored aftertaste of burn. 

A flooded chamber has the potential to ruin your entire vape, so the moment you get a whiff of a burning smell (or taste), stop vaping and start cleaning. Chances are, you're going to need to give the thing a pretty thorough once-over before it's working again. Making sure you hit your vape at least every few days—and take some smaller hits—will help keep your chamber nice and dry.

Faulty vape coil

Another culprit as to why your cart has airflow but no smoke is a faulty vape coil or heating element. A faulty coil can’t generate enough heat to produce vapor, so you end up drawing air without any of that satisfying smoke. To check, disassemble your vape pen and see if your vape coil is damaged. Additionally, if you’ve ever noticed a burnt taste before or a bubbling noise during use, it’s usually a sign that your coil is damaged and needs replacement.

Battery connection issues

If the battery isn't properly connected or if there's an issue with the battery itself, it won't provide the necessary power to the heating element. Check the battery's charge and pin and ensure it’s correctly attached.

Wrong settings

Your vape's airflow settings play a big role in how well it functions. While you're filling that bad boy up, the airflow holes should be 100% closed. And when you're taking a hit, those same holes should be wide open, so you're not forcing the liquid through a tiny little crack.

If your airflow holes are at all misaligned, it could be throwing off the entire balance of your vape and causing a clog. Make sure that you're checking your airflow before every hit to see if it needs to be adjusted. Avoid inhaling too hard and instead practice some gentle, consistent puffs.

Cart Has Airflow but No Smoke? Try These Fixes:

As you’ve read above, there are many causes as to why your cart has airflow but no smoke. The good news is that diagnosing or fixing the issue isn’t that hard. Before you consider replacing your vape pen, try these simple yet effective troubleshooting steps to get back to vaping:

  • Clean the cartridge: Regularly clean your cartridge to remove any residue that might be blocking the airflow.
  • Try out other cartridges: Check whether your cartridge is faulty by using a different (working) cartridge and see if that fixes the problem.
  • See if your cartridge really is compatible: Always use cartridges that are designed for your specific vape pen model to avoid compatibility issues.
  • Check your vape coil: Check the heating element for any signs of damage or wear. If it's faulty, consider replacing it.
  • Check for faulty battery connections: Ensure the battery is properly connected and fully charged. Loose connections can disrupt the power supply to the heating element.
  • Adjust the temperature settings: If your vape pen has adjustable settings, experiment with higher temperatures and see if it produces vapor.
  • Let the liquid settle:If you've just refilled the cartridge, give it some time to settle to ensure proper wicking.

To sum it up

No vape pen is immune to clogging. But by taking a few preventative measures and knowing how to fix the problem if it does arise, you can keep your device functioning properly for as long as possible. If you do end up with a clogged vape pen, don't worry—with a little elbow grease and patience, you'll be taking another great hit in no time.


Why is my cart getting airflow but not hitting?

This can be due to different factors. But most of the time, it’s due to a blockage or a malfunction in the heating element. It can also be due to battery connection problems, a flooded chamber, or the oil becoming runny or thicker due to the weather. Regular cleaning can address most of these issues.
