Letting the pen warm up first helps loosen any residue. However, turn the pen off before taking it apart and don’t touch it if it is too hot.
A lot of vape pens come packaged with cleaning brushes. You can usually order a replacement wherever the pens are sold.
Be gentle when handling the coil. That wire is the most delicate part of the pen and is most often the cause of a nonfunctional pen. Never use water to clean out the heating chamber. It has a lot of wires, so water will short-circuit it. Water can be used to rinse out the mouthpiece.
If it doesn’t work, the pen may need more cleaning or the wire may be out of place.
Make sure the pen feels cool before touching it. The pen most likely won’t heat at all if the coil needs adjustment. Don’t touch the coil if you feel heat coming off of it.
If the screws aren’t in place, your coil likely isn’t either. Take it to a vape pen shop to find replacement screws.
Avoid tightening the screws too much or else the coil won’t heat. Work in quarter-turns and test the coil as you go by turning on the power.
Turn the power off before touching the coil with the paperclip. Metal on metal can permanently break your pen.
Unfortunately, aligning the coil isn’t an exact science. Coils are finicky and it takes a little luck sometimes to find the proper positioning. The wire moves out of place easily as well. Dropping the pen, or even bumping it too hard, can cause it to shift.
Note your pen’s brand to get an exact replacement. Usually the replacement is a whole new heating element, so all you have to do is unscrew the old one and affix the new one by hand.
Never rest the hot iron against your work surface.
Again, make sure the pen feels cool before touching it. If a wire is broken, the pen should not heat up at all.
If you need more exposed wires, use wire strippers or a utility knife to cut off some of the casing. You can also rub the exposed filaments to fray them and make them easier to twist together. The red wire connects the battery to the heating element. The black wire is the ground wire and runs from the battery to the outside of the heating chamber.
Always move the soldering iron. Don’t let it hang over the exposed wires, or else it might begin to melt them. Use the tip to spread the soldering material.
Another way to cover the joint is with electrical tape.
The wires may have come loose from their connections. This is hard to fix at home, especially if you can’t locate the terminals for the wires. Bring the pen in to a professional.
