Introduction: When the Vapour Disappears
You take a draw, but your vape produces little or no vapour. Perhaps the flavour has faded, the device makes a gurgling sound, or every puff comes with an unpleasant burnt taste. Before assuming your entire device has failed, it is worth checking the coil.
A vape coil not working properly can result from several issues, including a dry wick, excess e-liquid, dirty electrical contacts, low battery power, incorrect wattage, or a coil that has reached the end of its usable life.
The good news is that some vape coil issues can be resolved with a few basic checks. Others, particularly a permanently burnt wick or damaged coil, require replacement.
This guide explains what causes poor vapour production, how to troubleshoot the problem step by step, and how to recognise when it is time for a new coil.
What Does It Mean When a Vape Coil Stops Producing Vapour?
A vape coil is the heating element inside a refillable tank or compatible pod. It typically consists of resistance wire and a wick that absorbs e-liquid. When the device activates, the heating element warms the liquid held in the wick, producing an aerosol commonly called vapour.
If your vape coil is not working, the problem usually comes down to one of these issues:
-
Dry or damaged wick: The wick cannot absorb enough e-liquid, or it has become burnt.
-
Faulty or worn coil: The heating element has deteriorated, reducing vapour production.
-
Electrical problems: Power is not reaching the coil properly because of poor connections or a device issue.
However, a vape that produces no vapour does not automatically have a faulty coil. Battery problems, poor electrical connections, blocked airflow, and device faults can cause similar symptoms.

5 Common Vape Coil Issues and How to Fix Them
Before you toss the coil in the bin, it helps to know which of the five usual culprits you're actually dealing with. Each one has its own fix, and guessing wrong just wastes coils and money.
1. Dry or Unprimed Vape Coil
The cause: The cotton wick inside the coil needs enough e-liquid to stay saturated during use. If the tank runs empty or a new coil is activated before the wick absorbs the liquid, it can overheat and produce a harsh, burnt taste with little vapour.
This is one of the most common reasons a new or recently used coil may stop working properly.
How to fix it:
-
Refill the tank or pod if the e-liquid level is too low.
-
If you have installed a new coil, follow the manufacturer's priming instructions.
-
For many refillable devices, allowing a newly installed coil to soak for around 5–10 minutes is a useful starting point. Thicker e-liquid or specific coil designs may require longer.
2. Flooded Vape Coil
The cause: A flooded coil occurs when excess e-liquid collects inside the coil chamber or airflow path. This can restrict normal airflow and cause gurgling sounds, leaking, spitback, or inconsistent vapour production.
Overfilling the tank or using an incorrectly fitted coil can contribute to this problem.
How to fix it:
-
Turn off the device and disconnect the tank or pod if the design allows it.
-
Wipe away visible e-liquid from the mouthpiece, airflow openings, and accessible exterior surfaces.
-
Check that the coil or pod is fitted correctly and that the device has not been overfilled.
3. Dirty or Loose Connections
The cause: E-liquid residue, moisture, or dirt can accumulate around the contact points between the coil, tank, and battery. If the coil is not seated correctly or the electrical contacts cannot connect properly, the device may struggle to heat the coil or fail to produce vapour.
Checking accessible contacts and ensuring the components are fitted correctly may help identify the issue.
How to fix it:
-
Switch off the device before inspecting it.
-
Remove the tank or pod if possible.
-
Check the accessible contact points for residue, moisture, or visible damage.
-
Clean accessible contacts with a dry, lint-free cloth or cotton swab, following the manufacturer's guidance.
4. Low Battery Power or Wrong Wattage Settings
The cause: A low battery may prevent the device from operating normally, while an unsuitable wattage setting can affect how efficiently the coil heats the e-liquid. Using power outside the coil's recommended range may also cause overheating, weak performance, or premature wick damage.
Always follow the manufacturer's recommended settings instead of increasing the wattage to compensate for weak vapour production.
How to fix it:
-
Check the battery level and recharge the device according to the manufacturer's instructions.
-
Confirm that the device is switched on and has not activated a lock or other operating restriction.
-
If the device supports adjustable wattage, check the recommended range printed on the coil or packaging.
5. Worn-Out Vape Coil
The cause: Coils are consumables, not permanent parts. They degrade with heat cycles, and sweet or dark e-liquids gunk them up especially fast, usually within 1 to 2 weeks of regular use.
With regular use, the coil and wick gradually accumulate residue and deteriorate from repeated heating. Sweetened e-liquids, frequent draws, and unsuitable power settings can accelerate this process, leading to muted flavour, reduced vapour production, or a persistent burnt taste.
Common warning signs include:
-
A burnt taste that persists after refilling.
-
Noticeably weaker flavour than usual.
-
Reduced or inconsistent vapour production.
-
Dark residue around the coil or wick.
How to fix it: Replace the coil with one that is compatible with your exact tank or pod system. A permanently scorched wick cannot reliably be restored through cleaning.
How Long Does a Vape Coil Really Last?
There's no single answer here, but there are solid averages. Plus-ohm coils, the higher-resistance type used for mouth-to-lung vaping, typically last around three weeks of moderate use.
Sub-ohm coils, which run hotter and are used for bigger clouds, tend to burn out closer to the one-week mark. How you vape matters just as much as the coil itself, and lowering your wattage is one of the easiest ways to stretch that lifespan out.
E-liquid choice plays a bigger role than most people expect too. Sweet or high-VG (vegetable glycerin) juices caramelise on the coil wire over time, which gunks it up and dulls the flavour well before the metal itself wears out.
If you're the type who goes through dessert-flavoured e-liquid daily, don't be surprised if your coil taps out closer to a week rather than two. If you're browsing for a reliable replacement, our Vaporesso coil collection covers most of the common resistance ranges people ask us about in-store.
Step by Step: How to Fix a Vape Coil That's Not Working
Here's the order we'd actually walk a customer through at the counter, from quickest fix to last resort.
-
Check the e-liquid level. Empty tank, dry wick, no vapour. Refill it.
-
Give a new coil time to prime. Let it soak 5 to 10 minutes before vaping.
-
Look and listen for flooding. Gurgling or a wet draw means wipe it down and clear the airway.
-
Clean the contact pins. A quick alcohol swab on both the battery and tank threads fixes more "dead" devices than people expect.
-
Charge the battery and check your wattage. Match the wattage to what's printed on the coil.
-
If none of that works, swap the coil. A quick SMOK coil replacement resolves the issue in most cases where the wire itself has simply burnt out.
How to Make a Vape Coil Last Longer
Coil lifespan cannot be extended indefinitely, but proper care can help reduce premature wear.
-
Prime new coils correctly. Allow the wick to absorb enough e-liquid before first use.
-
Stay within the recommended wattage. Excessive power can overheat the wick and shorten its usable life.
-
Keep sufficient e-liquid in the tank. Do not continue using a refillable device when the wick is no longer adequately supplied.
-
Allow time between draws. Repeated, rapid draws may prevent the wick from absorbing liquid quickly enough.
-
Use compatible e-liquid. Follow the device manufacturer's guidance on viscosity and VG/PG ratio.
-
Keep the tank and accessible contacts clean. Remove external residue and condensation according to the device instructions.
-
Replace worn components promptly. Do not continue using a coil that produces a persistent burnt taste or shows signs of damage.
Sweet or heavily sweetened e-liquids can leave residue that affects flavour and coil performance. However, switching e-liquid alone will not repair a coil whose wick has already burnt.

When to Consider a Vape Coil Replacement
Not every performance problem requires a new coil. Start by checking the e-liquid level, battery, settings, connections, and signs of flooding.
However, a vape coil replacement is usually the appropriate next step when the existing coil is burnt, damaged, or no longer performing properly after basic troubleshooting.
Look for these signs:
-
Persistent burnt flavour: The wick may have suffered permanent heat damage.
-
Continually muted flavour: Residue buildup or coil wear may be affecting taste.
-
Reduced vapour production: If battery power, airflow, and settings are correct, the coil may have deteriorated.
-
Visible damage or heavy residue: A damaged or badly degraded coil should not be kept in service.
Replacement coils are designed for specific devices, tanks, and pod systems. Before ordering, confirm the product's model name, resistance, and compatibility with your current setup.
For SMOK devices, explore compatible SMOK coils and compare the listed options with the specifications for your device. Choosing a compatible component is more important than selecting a coil based on appearance or price alone.
Tired of Coil Hassle? Here's an Easier Option
If priming new coils, checking wicks, and keeping replacement parts on hand feels like too much maintenance, a disposable vape offers a simpler alternative. Unlike refillable devices that require compatible coil replacements, disposable models have an integrated heating element, so there is no separate coil to install, prime, or replace during normal use.
The Rifbar MixPro 40K Sour Apple Ice is one option to explore if you prefer a device without routine coil maintenance. Its integrated design removes the need to manage separate coils, making the setup more straightforward for adult consumers who want to avoid the upkeep associated with traditional refillable systems.
However, disposable devices are designed for a limited service life and cannot be maintained in the same way as a refillable vape. Before choosing one, check the product specifications and follow the manufacturer's usage and disposal instructions.
Final Thoughts on Vape Coil Issues
When your vape coil stops producing vapour, the cause may be as simple as a depleted battery, a connection problem, or an unprimed coil. In other cases, flooding, unsuitable power settings, or a worn wick may be responsible.
Start with the basic checks: confirm the e-liquid level, inspect the device, review its power settings, and look for signs of coil wear. If the problem persists and the coil is burnt or damaged, replacement is generally the most appropriate solution.
For users of compatible SMOK devices, VapeItOff's SMOK coil collection provides a place to review replacement options. Always match the coil to the exact device model and follow the manufacturer's instructions.
