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

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 or pod vape 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 with a Vape Tank

1. Try Another Tank/ModTry 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 PointsClean 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.

How to Fix Check Atomizer/No Atomizer On A Pod Vape

If your pod vape isn’t firing, has a blinking LED and won’t fire, or says Check Atomizer or No Atomizer, you can follow a few of the same steps listed above for tanks:

1. Clean Your Contact PointsClean Pod Contact Points

The first step you should try if your pod vape isn’t firing or says check atomizer is cleaning out your contact points. Take the pod out of your pod vape and check the bottom of the pod for any dirt or ejuice. Also check inside your vape where the pod attaches to it. If you see any ejuice or dirt, clean it out with a paper towel then reinsert the pod and try again. 

Dirt or ejuice can prevent a proper connection between your pod and the device and this can cause the device to not fire or to throw a check atomizer/no atomizer error. 

In addition to dirt and ejuice potentially causing a bad connection, ejuice can also get into the circuit board of some pod vapes and cause them to malfunction. If you see a lot of ejuice under the pod in your device, this could potentially be the reason it’s no longer working properly. 

If cleaning your contact points doesn’t resolve the issue and your pod vape still isn’t working then move on to step two.

2. Check Your Contact Points for DamageCheck Pod Contact Points for Damage

If cleaning the contact points doesn’t fix the check atomizer error on your pod vape, you’ll want to carefully examine the contact pins/plates on your pod vape and on your pod for damage. 

Some pod vapes have spring-loaded pins that can become stuck in a pushed down position. You’ll want to check and see if this is the case with your pod vape. If you see a stuck pin, you can try to lightly push it down with a small screwdriver to get it out. If this doesn’t work, using a paper towel to try to clean out around the pin may get it to pop back up.

Other pod vapes have solid pins or contact plates that can be bent or otherwise break. Check to see if any of your contact points are bent, worn out, or broken. If a contact point is bent you may be able to carefully bend it back into its correct position. If you see a broken contact point, this usually isn’t salvageable and the device will have to be replaced or repaired through your manufacturer’s warranty (if the device is still within the time-frame).

3. Reseat your Coil/PodReseat your Pod or Coil

Sometimes the most simple fixes are the most effective. If your pod vape uses replaceable coils you can try removing the coil and reinserting it into the pod. Ensure that you’re lining up the coil properly if there are any notches that need to be lined up and that the coil is snugly, firmly, and properly seated in the pod.

If your pod vape uses a replaceable pod then you can try removing the pod, rotating it 180°, and reinserting it into your device. Sometimes this can fix the issue. Also, make sure that your pod is completely inserted into your pod vape. Some devices have pods that magnetically attach, but also need to be pushed down to ‘click’ into place properly with the device.

4. Try Another Coil/PodTry Another Pod or Coil

If you’ve tried all of the above steps and nothing is working, the problem could be that your coil or pod has an issue. Try using another coil/pod.


Getting an error message on your vape is frustrating. Hopefully the steps up above have helped you get back to vaping. If this guide helped you, share it with your friends who vape!

  • 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?

    • If you’re talking about the pin inside the 510 connector of your mod, you’ll probably have to take the device apart to be able to fix that. Even then it’s not a guarantee it will work again. If it’s an older mod then it’s probably better to save yourself the headache and get yourself a new mod. No easy fix for this unfortunately ):

  • 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 ….

  • 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 💟

  • Well I dropped it on the floor and it’s started saying no automizer what should I do I have a ijoy box mod

  • 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!!!

  • My vape still isn’t working and I went through all these steps to try and fix it I’m not sure what to do to fix it it’s to expensive to replace

    • Hi Harley. If you followed all the steps and none of them worked then you could try contacting the manufacturer and seeing what their options are for repairing/replacing. It’s unfortunate but I can’t think of anything else that can be done.

  • Cant get the tank to work on multiple devices. Started off with a “check atomizer” message so went threw all the steps to reset but now getting “short circuit” message. I dont have any issues with my previous tank only switched due to issues getting filter. Is there anything that can be done to fix the issue

  • There are 2 small pieces of metal on each side of the coil that fit into 2 notches when you insert it. Make sure they are in place 🙂

  • Hi. I have a vopoo drag 2 with chargable batterys. My coil was dead so i took it out and started cleaning my vape. I changed the coil and then i saw the check atomizer thing. Ok so i cleaned the contact points, but it still was there. I even changed back to the old coil, the same thing. Before i cleaned it all worked good, mybe it showed new coil thing but thats it. Did i broke it when cleaning?

    • Hey Cj,

      I would check if the 510 Pin (the little gold pin at the very bottom of the tank, where you screw it into the mod) is loose. I would also make sure you’re installing the coil correctly. Make sure to follow all the steps outlined in the article because it’s very unlikely that you broke it while cleaning unless you were very rough.

  • Thanks for the tips. It worked out great. I have a falcon king tank and aegis x mod. When I finally do break it cause eventually i will. Do you have any advice on a new mod and tank? Is there any better mods and tank in your opinion?

    • Hey Kyle,

      The Falcon King and Aegis X mods are two of the top mods/tanks out there right now. The new OFRF NexMesh Pro Tank is really good though and I recommend checking it out. As for mods, the Aegis X is the best combination of durability and performance, can’t go wrong with it! I do like the lightweight of my Gen S, though.

  • I just bought a new mod and a horizon tank to go with it and I got this error and immediately thought I’d have to save up for a whole new mod. Thank you so much, I tried popping the 510 out from my tank and putting it back in place and it worked. Thanks so much! Literal life saver

    • For a pod vape you can follow a few of the same steps listed above for tanks:
      1) Clean your contact points (the bottom of the pod and the inside of the battery)
      2) Check the pins on the inside of the device to see if they’re damaged or pushed in.
      3) Take out the coil from the pod and re-insert it. Make sure it’s in there snug and properly.

  • Thank you for the making this easy for a first timer with this error. I did purchase a new mod but I couldn’t let it go! “WTH is this No Atomizer even mean??? My mod is working great now, thanks to your awesome tips and instruction.

  • I have a Horizon Tech Falcon that says it’s too hot after 1 or 2 puffs. I’ve cleaned it, changed the coil to no avail. It was a gift so I have no warranty.
    I thank you for any help you may be able to give.


    • Yeah i juat bought a vivant vault and i just opened it and it says no atomizer what the hell do i do

  • Thanks very much !
    The coil was a dud, worked fine for awhile but went bad after a few days.

    • If you follow all of the above steps it should help you. But specific to that device, make sure the coil is properly screwed into the airflow controller. Also, check the pins inside the micro (the ones that the coil/airflow controller makes contact with) and make sure they aren’t stuck pushed down.

  • My vapor is not working properly it’s says check atomizer on a mini snowwolf vapor.
    I’ve cleaned it out and it still won’t work. I took it to the shop but they didn’t fix it so what do I do now

    • If none of the steps listed in this article are working then you probably have a deeper issue with the mod. If it’s still within the warranty period then you can contact SMOK.

  • Brand new Vapresso Gen S gives me check atomizer signal tried the tank on Rincoe Mato Pro still says check atomizer

    • If you tried the same tank on another mod and it still says check atomizer then it’s a problem with the tank. Try steps 2,3, & 5 from the first section of the guide “How to Fix Check Atomizer/No Atomizer with a Vape Tank“. Hopefully this will get the tank working again!

  • I used my wireless charging nano blue light atomizer once and it worked great but when i tried to use it again after trying to charge it , it would not work. Itook off the bottom and clean it still not charging nor spraying but blue light will come on. please help.

    • While the “Nano Blue Light” is technically an atomizer, it is not a vape and so I’m not sure how you would fix this issue with your mist fogger not working.

  • I have tried all of the suggestions. My pins aren’t stuck pushed in, the device is completely clean same with the pod. I’ve changed the coils and tried a different pod but I still get the ‘no atomizer’ message. I have no idea whats wrong can anybody help?

    • I’m not sure exactly what you mean, but in 99% of tanks the open end of the coil needs to be inserted into the tank and the “flat” end needs to be facing the bottom of the tank.

  • I have 2 vandy vape guar mods I’ve tried everything to fix this ongoing problem. When sub ohm tank is threaded down to snug device reads ” short circuit” if I unscrew tank almost 2 turns it fires. Can you help me please?

    • This sounds like the wiring underneath the 510 connector is messed up somehow. Aside from taking it apart yourself and checking it, you should contact vandy vape about this issue.

  • Petroleum jelly conducts electricity. Very ell, in fact. If you keep getti g No Atomizer prompt Apply some to contact points. That fixed the No Atomizer bs.

  • Thanks for the information. Had a voopoo drag for over a year and it died because of a short. Got a brand new one and said “check atomizer”. It was a short on the filter. Looks like the connection soldered broke. Might try to fix it later if I have everything I need. But you helped me find the problem. Think these voopoo are the best so far.

    • Love the Voopoo mods. I’ve bought 3 different ones (because I like to switch mods from time to time) along with many different brands and the VooPoo are fantastic. My fave is the VooPoo Gold Drag. I just keep going back to it.

  • I have 3 vapes that say no atomizer and I have done all the steps on all 3 and it is still a no atomizer! This makes me sick. It’s like they are good for about a year and then bam no good! I would like to know how to take them apart and fix them. This is to expensive to keep replacing them and if it damages them further , there is nothing list. They were already damaged goods

    • Hello Jackie,

      If you’ve followed all of the steps and they still say no atomizer, it’s likely an internal issue. I wouldn’t recommend taking apart your vapes yourself but if you are going to do it, make sure that they are turned off and that you remove the battery if they are external battery powered.

      We’re unable to give guidance as to how to disassemble vaping devices but it should be pretty straightforward once you start removing the externally visible screws. Again, I wouldn’t advise taking on these repairs yourself as there is the possibility that you could get hurt if they are internal battery mods.

      • I just bought the Aspire Zelos 3 yesterday with an extra tank. They both worked perfectly. I went to bed and left the power on ( which shouldnt matter) when i woke up to have a hit it says check atomizer. i changed the tank and still the same thing. i then changed the coil in one and the same thing. I then cleaned the terminals and still nothing. The unit must be a dud. I spent 270 ish dollars and was shipped across Canada which i also paid for over night delivery. What a headache!! ah

  • Mine is brand new and this is nit my first E60. The new tank fills from the side and has a brand new coil and works fine with a different tank. Should I just throw the one away that came with it along with few new coil or remove the coil and replace it? Or just buy another coil and tank?
