If you've never used it, it's a DOA arrival and most suppliers will replace them. It happens. Have you had it a while or did you receive it recently? If you just got it, contact your supplier and see what they'll do for you. If you've had it a while, explain that you've been using cartomizers exclusively and that's why you didn't catch the DOA right away. You've got nothing to lose by trying.
I think I will do that. I purchased the kit from Liberty Flights and they've been extremely helpful.
