How to Fix Check Atomizer/No Atomizer On Your Vape Mod

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 vape 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


How to Fix Check Atomizer/No Atomizer with a Vape Tank

1. Try Another Tank/Mod

Try Another Tank or 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.


2. Clean Your Contact Points

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.


3. Check the 510 Pin on your TankCheck Your 510 Pin On Your Tank

If the 510 pin on your tank is damaged (where it connects to the mod) then this will cause a “Check Atomizer” or “No Atomizer” error. This is because your tank isn’t making a proper connection with your mod. Fortunately, sometimes it’s an easy fix.

If you can unscrew the base of your tank then do so. Inside the bottom section of the tank (usually the airflow control ring) there should be a plate. Push this plate down from the inside so that the 510 pin is sticking out again from the bottom of the tank. If it doesn’t push down then you might have to turn the plate to screw it back down.

Reassemble your tank and check to see if this fixes the error.


4. Check the 510 Connector on your ModCheck Your 510 Connector On Your Mod

Just like the 510 pin on your tank being damaged, a damaged 510 connector on your mod will also cause a “Check Atomizer” or “No Atomizer” error for the same reason: the tank isn’t properly connecting to the mod.

Unscrew your tank from your mod and take a look at the 510 connection. If it looks like it’s pushed in too much then this could be the issue. Most 510 connectors are spring loaded and sometimes they can get stuck.

Take a screwdriver and gently push down on the 510 connector inside of the mod. This can help ‘reset’ the pin and allow it to spring back up. But if this doesn’t work there isn’t much else you can do.

You have four options at this point:

  • Send it in to the manufacturer if you’re within the warranty period
  • Take it to your local shop for help
  • Try to fix it yourself and risk damaging the mod even further
  • Buy a new mod

5. Reseat Your CoilReseat Your Coil

Sometimes a check atomizer error can be caused by your coil. If cleaning your contact points didn’t work then 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 left 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 with the mod 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 then you may have received a dud. It sucks, but it does happen.


How to Fix Check Atomizer/No Atomizer/Atomizer Short with an RDA/RTA/RDTA

If you’re using an RDA and your mod is displaying a “Check Atomizer” or “Atomizer Short” error then you should first follow steps 1-4 from the previous section. If that doesn’t help then you can try the following to get it working again:

1. Did you Build Too Low?Did You Build Too Low

If your build resistance on your RDA is too low some mods will deliver an error message. This is a safety feature on some mods and it’s there to keep you safe. You should always be using an Ohm reader or regulated mod to build your coils. But more importantly, you should always know Ohm’s Law and practice proper battery safety.

Make sure that your build isn’t too low for your mod and try again.

2. Check for Loose Pieces of Wire

With an RDA there could  be left over pieces of wire stuck in the build deck. Loose pieces of metal on the build deck will cause your mod to display “Check Atomizer” or “Atomizer Short”. Even very small pieces or trimmings of wire can cause a short or a check atomizer error on an RDA/RTA/RDTA.

First, inspect the build deck closely for loose pieces of wire or other foreign objects. If you find something, remove it and test your RDA/RTA/RDTA on your mod. If it’s still reading “Check Atomizer” or “Atomizer Short” then move on to the next step.

3. Make sure your Coils are Installed ProperlyMake Sure Coils Are Installed Properly

This might seem obvious but it’s always worth checking. You might think that you installed your coils properly into the build deck but some rebuildable decks can be confusing. You might have installed the coils into the wrong terminals. Make sure that your coils are installed with one leg in a positive terminal and one leg in a negative terminal. This small oversight can often cause the dreaded “Check Atomizer”, “No Atomizer”, or “Atomizer Short” errors.

4. Are your Coils Touching the Build Deck?

If your coils are touching the build deck then this can lead to error messages on your vape. Be sure that your coils are installed properly and that only the legs are in contact with the build deck. Reposition your coil using a screwdriver or coiling rod if it’s touching another part of the build deck.

  • Yeah, no atomizer is a death sentence for a mod. Don’t chare on yr car charger. While driving, the alternating current just wreaks havoc with the eltronics on mods. Mine is now deceased. Live and learn.

  • I just got the mvv2 from dovpo out of the box it won’t pick any build on any atomizer I don’t keep receipts so I can’t send in for warranty any suggestions on a possible fix

    • Hey Rick,

      I’m not sure what is specifically wrong here but it must be a faulty mod if it isn’t picking up ANY atomizer. This might be silly but, check to make sure that there’s nothing in the 510 connection and that you’re fully screwing down your atomizers.

  • Mine is reading no atomizer, & have done all suggestions. The button inside the battery has been pushed down to far, I believe, from over tightening, over time. If I hold down tight, it will read. Any way to raise inside button back up a bit, or is it shot?

  • I REALLY want to thank you guys for making a simple an easy to understand web page so any1 can do your VERY EXCAT DIRECTIONS ON HOW TO FIX ISSUES!!
    im supposed to have major reconstructive surgery on my neck an shoulder at the end of this month an have to quit smoking ….then my vapes atomizer wasnt reading on the mod im not a “electronically inclined ” person i tend to mess them up more then fix …. But YOUR page gave me the confidence to at least try an ….
    IT WORKED EFFORTLESSLY AN I THANK YOU !!!

  • I would like to add to this,
    My Tank is a Ello Eleaf 4ml small tank.
    At the base of the tank where the 510 threads are that section is pressed fit onto the base.
    sometimes i have noticed that it gets loosened and needs to be repressed i use pliers and give a couple good squeezes.

  • Thanks this totally did the trick. I had a tiny piece of something in the bottom of my atomizer the size of a grain of sand. Something so tiny but caused the failure. Your advice solved my problem.

  • If I keep my mod at a 30-70°angle while not using it it stops saying check atomizer. Figured this out by accident when I changed the coil 3 diff times with 2 diff tanks, but still kept getting the same message after it would work once or twice and then quit. If I hold it upright too long or accidently put it down on the counter too hard to refill my tank it gives me the error message. I’m just glad I found a solution for now because I cannot afford to replace it until Friday.

  • OMG thank you so much! I think i didn’t tighten the coil in properly. Also i was a little slack woth the cleaning hehe. I saw the error message and freaked! Thanks 💟

  • Hi I have this product been working fine up to about an hour ago all of a sudden it has stopped working firs it had vape cutoff set in menu and now its reading check atomizer I have follo6all the tips but still not working can you please help as I sent alot of mi eye in it and I love this product

  • Just brought a brand new Smok Majestic and it keeps coming up check atomiser. I have anogher Smok vape, the new bowl and coil works fine on it. Does this mean there is a fault with the new mod

  • I considered the steps one by one. I have an Aspire Nautilus 2S and a Zelos mod.
    What did it was to screw the coil into its seating as tightly as I could.
    So thanks for the advice.

  • Thanks for this I was getting the dreaded message on an old Smok I recently found, that I forgot I had.

    Wasn’t the tank as I fitted 3 or 4 different ones, that were all working on other mods.

    So I depressed the 501 connector and wiped it with some kitchen roll and thst was it, message gone and now I’m vaping my retro Amok mod….complete with flashing coloured lights!!

  • OMG thank you so much, I was so pissed off my Mod was saying Check Atomizer and I had the Dual Coils connected ++ –!!

    THANK YOU!!!
