It is potentially answerable with more information, but not now. Really pics, if you don't know what is being asked and how long have you had it, in case it is warrantable in which case you probably want to head over to Geekvape's forum.
Which is a) full of Geekvape enthusiasts in general who will ask you all the same stuff as above, only maybe more in detail and assist or b) if it needs a warranty and you are nearing the end, Geekvape itself can assist you they are usually pretty responsive.
But we are FAR away from warranty-land at this point, too many unknown variables. Etc.
Welcome though. The more information you give, the better responses you will get. Really.
