don't know if is a problem of the board or what happened but not sure how to fix it. Is a old shark , dropped few times but always good to go . Is been my everyday device for the last 2 years . Today something weird happened . I have a Clapton coil in it and keep reading a temperature even when TC is switched to off. For that reason does preheat etc and keep sending weird w out. Anybody know how to reset or stop this ?
