Be careful not to over-tighten the atomizer, as it can break the 510 connectors.

Vape coils usually last from 1 to 4 weeks. However, certain juices can wear out your coils more quickly.

You can try unclogging it by removing it from the device and blowing through the mouthpiece. [4] X Research source

Use a lint-free cloth or paper towel to clean the connector pins and posts on your atomizer or pod, as well as on your battery or device. Twist the cloth into the hole in the atomizer tank to absorb excess liquids. If you use a paper towel, make sure there’s no paper residue on the connectors when you reconnect. For buildup around the 510 connectors, you use a paperclip to gently scrape away the gunk.

Are the plates damaged on either side? Is the screw threading intact? If you find any damage, you’ll need to replace those parts. Is the plate pushed up too far on the atomizer or pod? If it is, gently try to maneuver it back into position. If the pins on your mod are recessed too far, they won’t make contact with the atomizer. This can occur from overtightening the tank, dropping your e-cig, and even manufacturing defects. Gently tap the pins with a toothpick to see if they’ll spring back into place. If you’re unable to get the pin(s) back into place or suspect the pin(s) is/are damaged, you won’t be able to get rid of the “No Atomizer” or “Check Atomizer” message until you repair or replace the device. If you have an RDA or RBA with screws securing the pin to the device, you might need to tighten or loosen the screws to get the pin into its proper position.

Depending on your mod, there could be a firmware update that resolves the issue. Many vape manufacturers offer software updates to fix known problems. Check the manufacturer’s website for an update. If a reset or firmware update doesn’t get rid of the atomizer errors, it’s likely time to replace either the atomizer, the mod, or both. Replacing the atomizer will be the more affordable solution, so try that first. If that doesn’t help, replace your mod.
