Every mod coil (the part of your e-cig which heats up and vaporizes the vape liquid) has a limited lifespan, but exactly how long it will last depends on a number of things, including how often you vape and what kind of juice you’re using.
So, how do you know when the time has come to replace your coil? Essentially, it’s when the wire coil has worn out or the wick has burned, which could be anywhere between every one to four weeks.
Here we’re going to look at some of the signs that suggest it might be time to replace your mod coil.
Probably the first thing you’ll notice when your coil needs changing is a dry, burnt taste, no matter what flavour of e-liquid you’re using.
This is the most common symptom of a worn out coil and is an instant sign that it needs to be replaced.
While cleaning the coil may rectify the problem temporarily, it’s ultimately on its last legs by this stage and you’re only prolonging the inevitable. And, if you do continue to use your e-cig, you run the risk of causing damage to the other components so it’s probably best to get it changed sooner rather than later.
Other Strange Tastes
While a burning taste is the most common indicator a coil needs to be changed, you should also be wary of any other strange tastes.
It’s difficult to put your finger on exactly what it is, but if your e-cigarette is just tasting a little bit off, you’ll know what we mean. Sometimes you just know that something isn’t right!
While you might think that it’s nothing to worry about, it could be a problem with the coil, so it’s worth replacing it to see if this solves the problem.
One cause of this is that when you change your liquid, the flavour of the old liquid can linger in the coil.
A leaky e-cigarette could be a symptom of many problems, not just an old coil, such as a worn out O-ring or an overfilled tank.
However, it could also mean that your coil is coming toward the end of its life, so it’s worth carefully taking the e-cigarette apart and taking a look at the coil to see if this is the cause of the issue.
If not, check this blog from Vaping 360 for some more potential solutions to your leakage problem.
Again, strange gurgling noises coming from the e-cigarette doesn’t necessarily mean it’s time to change the coil, but it could be one of the causes.
Try swapping out your coil and seeing if that puts a stop to the worrying noises because if it doesn’t, there could be a bigger issue causing the problems. If the gurgling continues, here are some more potential causes.
You’ve Been Using It for a Long Time!
While all of the above are tell-tale signs worth looking out for, each vaper is different and you’ll know better than anybody else when you’ve been using a coil for a little too long.
If you vape fairly frequently, this could be as little as a week, but if you only use it moderately it could be as long as a month, so use your judgement to decide how long is too long.
Replacing the Coil
So now that you’ve decided your coil needs changing, how do you go about doing so? It’s actually a lot easier than you might think.
First, remove the battery from the tank and remove the tank cap. You’ll probably want to clean out the tank while you’re doing this too because the old coil has probably burnt out the e-juice in it.
Unscrew the coil from the tank cap and throw it away and give the cap a wipe down before screwing in the new coil and putting the tank back together.
Let the e-cigarette rest for a little while before using it, as the wick needs to soak up some e-juice before you do so.
If you don’t do this, the wick will be too dry and the heat from the coil may just burn it straight away!
