How to Fix a Burnt Device Coil: Causes and Solutions

Few things ruin a good device session faster than a burnt taste. That acrid, unpleasant flavor means your coil is not performing properly. Understanding why coils burn and how to fix (or prevent) burnt hits will improve your device use experience and save you money.

What Causes a Burnt Device Coil?

1. Dry Hits (Most Common Cause)

A dry hit happens when there is not enough flavor liquid on the wick, and the coil heats the dry cotton instead. This causes the cotton to burn, producing that terrible taste.

Common reasons for dry hits:

• Flavor Liquid level is too low
• Not priming a new coil properly
• Device Use too frequently (chain device use)
• Wick not saturated enough between draws
• Thick high-VG flavor liquids that do not wick well

2. Coil Gunk Build-Up

Over time, residue from flavor liquid sweeteners and flavorings builds up on the coil. This gunk caramelizes and eventually burns, causing off-flavors.

Flavor Liquids that cause more gunk:

• Very sweet flavors
• Dessert and bakery flavors
• Cinnamon and other spicy flavors
• Dark-colored flavor liquids
• High VG blends

3. Wattage Too High

Device Use at too high a wattage for your coil can cause it to overheat and burn out prematurely. Every coil has a recommended wattage range – staying within this range is important.

4. Old, Worn-Out Coil

Coils do not last forever. Even with perfect care, they eventually wear out. The coil wire degrades, and the wick becomes coated in residue, leading to burnt flavor.

5. Improper Priming

When installing a new coil, you must prime it by wetting the wick with flavor liquid before use. If you skip this step, you will burn the cotton on the very first hit, ruining the coil immediately.

6. Flooded Coil

While less common, a flooded coil can also cause issues. Too much flavor liquid can lead to gurgling, spitting, and sometimes burnt flavor if the excess liquid is not properly vaporized.

Signs of a Burnt Coil

Immediate Warning Signs

• Burnt taste – The most obvious sign. An acrid, burnt, or charred flavor
• Dry hit – A harsh, unpleasant hit that feels dry and scratchy
• Gurgling sounds – Can indicate flooding or coil issues
• Spitting – Hot flavor liquid droplets hitting your mouth

Gradual Signs

• Reduced flavor – Flavor Liquid tastes muted or off
• Less vapor – Noticeably less vapor production
• Off-flavors – Everything tastes slightly burnt or unpleasant
• Color change – The coil looks dark or blackened

Can You Fix a Burnt Coil?

The Short Answer

Once a coil is truly burnt (the cotton wick has been charred), it cannot be fully fixed. The burnt taste will persist, and the coil needs to be replaced.

When You Might Salvage It

If you caught it early and the burn is minor, sometimes you can improve things temporarily:

• Take a few gentle draws without firing to draw more flavor liquid to the wick
• Give the coil time to re-saturate (5-10 minutes)
• Try turning down the wattage
• This works best if the burnt taste is very mild

However, this is usually a temporary fix at best. The coil will continue to degrade, and you will need to replace it soon.

How to Replace a Burnt Coil

For Pod Systems

1. Remove the old pod from the device
2. Take out the new pod or replacement coil
3. If replacing just the coil, prime the new coil by adding a few drops of flavor liquid directly onto the wick openings
4. Fill the pod with your preferred flavor liquid
5. Let it sit for 5-10 minutes to fully saturate the wick
6. Reinstall the pod
7. Start with a few gentle draws at lower power if possible

For Tank Systems

1. Drain remaining flavor liquid from the tank
2. Disassemble the tank to access the coil
3. Unscrew and remove the old coil
4. Prime the new coil by applying flavor liquid to the cotton wick ports
5. Screw the new coil into place securely
6. Reassemble and fill the tank
7. Wait 5-10 minutes before device use
8. Start at a lower wattage and gradually increase

How to Prime a Coil Properly

Proper priming is the best way to prevent burnt coils:

1. Apply 2-3 drops of flavor liquid directly onto each wick opening on the coil head
2. Apply 1-2 drops down the center of the coil where the wick is exposed
3. Assemble and fill your tank/pod
4. Wait 5-10 minutes (yes, really – patience is key)
5. Take 3-5 gentle dry hits (without firing) to pull flavor liquid through the wick
6. Start device use at a slightly lower wattage

Tips to Prevent Burnt Coils

1. Keep Your Tank Topped Up

Do not let your flavor liquid level get too low. When the liquid level drops below the wick ports, the coil will not get enough flavor liquid and will burn. Refill when you get down to about 20%.

2. Prime New Coils Properly

This cannot be overstated. Always prime new coils and give them time to saturate. A minute or two is not enough – wait at least 5 minutes, preferably 10.

3. Avoid Chain Device Use

Taking multiple draws back-to-back without giving the wick time to re-saturate can cause dry hits. Give at least a few seconds between draws.

4. Use the Right Wattage

Stay within the recommended wattage range for your coil. If you are getting dry hits, try turning the power down slightly.

5. Choose Flavor Liquids Wisely

• Very sweet flavor liquids gunk up coils faster
• High VG flavor liquids are thicker and may wick more slowly
• If you go through coils quickly, try less sweet flavors or higher PG blends

6. Break in New Coils Gradually

Start at the lower end of the recommended wattage range and gradually increase over your first few draws. This helps the wick and coil adjust gradually.

7. Store Devices Properly

• Store upright to keep the wick submerged
• Avoid extreme temperatures
• Do not leave devices in direct sunlight or hot cars

8. Clean Your Tank Regularly

When changing flavors or coils, give your tank a good clean. Built-up residue can contaminate new coils and cause them to burn out faster.

Troubleshooting Common Coil Issues

Burnt Taste With a New Coil

Cause: You did not prime it properly, or you did not wait long enough before device use.

Solution: Unfortunately, the coil is probably ruined. Replace it and be sure to prime the next one properly.

Coil Burns Out Too Fast

Cause: Could be high wattage, sweet flavor liquids, chain device use, or a defective coil.

Solution: Try turning down the wattage, switching to less sweet flavor liquid, or taking more breaks between draws. If it keeps happening, try a different brand of coils.

Gurgling and Spitting

Cause: Flooded coil – too much flavor liquid, or the coil is not screwed in properly.

Solution: Remove the tank/pod and blow gently through the mouthpiece (away from your face) to clear excess flavor liquid. Check the coil is tight. Wipe away any excess liquid.

No Flavor / Weak Flavor

Cause: Could be a dying coil, device user tongue, or the wattage is too low.

Solution: Try increasing wattage slightly. If that does not help, the coil may need replacing. Also, make sure you are not experiencing device user tongue (taste fatigue).

Frequently Asked Questions

Can you clean a burnt coil?

For pre-built coils (the type most people use), you cannot really clean them once the wick is burnt. Some people try soaking coils, but this rarely restores them to good condition. It is usually better to just replace the coil.

How long should a device coil last?

Most coils last 1-2 weeks with average use. Heavy device users might need to replace weekly, while light device users might get 3-4 weeks. It depends on your usage, flavor liquid choice, and wattage settings.

Is a burnt device coil dangerous?

While a burnt hit does not taste good, an occasional one is not considered dangerous. However, consistently device use with a burnt coil means you are inhaling degraded and potentially harmful compounds. It is best to replace burnt coils promptly.

Why does my new coil taste burnt?

If a brand new coil tastes burnt, it almost always means you did not prime it properly or did not wait long enough for the wick to saturate. The cotton wick needs time to absorb flavor liquid before you heat it.

Can I still device with a burnt coil?

You can, but you probably will not want to – the taste is terrible. Additionally, device use with a burnt coil may expose you to degraded compounds from the burnt wick. It is better to replace it.

Conclusion

Burnt coils are an unfortunate part of device use, but they can be minimized with proper technique. Always prime new coils, keep your tank topped up, avoid chain device use, and use appropriate wattage settings. When a coil does burn out, replace it promptly for the best flavor and experience.
