It’s the message that no vaper wants to see: the dreaded “Check Atomizer” or “No Atomizer”.
All vapers will experience this problem at some point in their journey, and it can happen suddenly and without any apparent cause. Thankfully, while a bit frustrating, this is an easy problem to fix.
“Check Atomizer” or “No Atomizer” will appear when your mod isn’t reading your coil correctly. This can be due to the 510 connector not reading properly (where the tank screws onto the mod), the coil not making proper contact inside of the tank, or possibly a short.
Simply put, if your mod can’t read your tank and coil resistance properly, it won’t be able to deliver power and therefore won’t work. In this quick guide you’ll learn how to fix this common annoyance, and you’ll be back to vaping in no time!
How to Fix Check Atomizer/No Atomizer On Your Vape Mod
Try Another Tank/Mod
This is the best way to know if there’s truly a problem. If you have another tank handy, you can try doing a switch. Take the tank off of your current mod and replace it with another tank. If your mod is reading the new tank correctly, it could be a problem with the coil on your other tank. You might also want to clean the contact points on the tank that was giving you the error.
If your mod is still reading “check atomizer” with a new tank, it’s probably a problem with your mod.
You can also see if your tank reads “check atomizer” on another mod. If you put the tank on another mod and it gives you the same error, it’s almost definitely a problem with the contacts on the tank or the coil inside. See our next two tips.
Clean Your Contact Points
Over time, dirt, dust, and ejuice can collect in your 510 connector and this can cause your mod to read Check Atomizer/No Atomizer. Start by removing the tank from the mod and inspect the threading where the tank screws in for dirt, dust, or ejuice. Do the same with the 510 connector on your mod.
Clean out the contacts with a paper towel, and screw your tank back onto your mod. Ensure that your tank is on firmly, but take care not to overtighten it. Check to see if this fixes the problem. If not, try our next solution.
Reseat Your Coil
Sometimes, the check atomizer error can be caused by your coil. If cleaning your contact points didn’t work, you can try reseating your coil. You’ll want to take apart your tank as if you were changing the coil. Unfortunately, this can be a little bit messy and isn’t always convenient to do if you have a considerable amount of ejuice in your tank.
Once you’ve taken apart your tank, unscrew your coil from the base of the tank. Now, you’ll want to clean the bottom of the coil, where it screws into the tank and makes contact. You’ll also want to clean your tanks contact point as well. Once done, reseat your coil, and reassemble your tank. Check to see if this fixes the Check Atomizer error. If your tank still reads the same error after following the previous steps, it might be time for a new coil. If the coil is relatively new, you may have received a dud. It sucks, but it happens.
How to Fix Check Atomizer/Atomizer Short on an RDA
If you’re using an RDA, you can try the same steps as the above. Obviously reseating your coil will be different than when using a subohm tank with premade coils. You’ll have to unscrew your leads, reseat your coils, and tighten your leads.
Check for Loose Pieces of Wire
With an RDA, there could also be left over pieces of wire stuck in the build deck. Even very small pieces or trimmings of wire can cause a short or a check atomizer error on an RDA. Inspect the build deck closely for loose pieces of wire or other foreign objects, and test your tank again.
