First of all, you have to know why your Vape Pen Blinking 3 Times.

Why does my vape pen blink 3 times?
Some batteries vape pens will blink 3 times to indicate a short circuit. Most standard e-cig batteries have a so-called short-circuit protection function, so if you press the trigger button, it will blink only three times, and then do nothing, to show it may have a short circuit occurs.


Here are some vape tips to fix this issue.
Remove the tank, ensure the battery is turned on and press the fire button to check.
To check the battery only.
Does it still blink 3 times with no tank?

If the LED still flashes 3 times without the tank you know it's something to do with the battery, if it only flashes when it's connected to the tank it could be the that there isn’t a good connection, or it could be the coil head.

If the tank is screwed down too hard it can push the centre pin on the battery down just a tad and the connection is lost. Just check the battery isn’t screwed on too tight. Try backing it off a bit and see what happens.

Also try another coil in case that’s the problem, depending on what you’ve already discovered above.
