I'm having a similar issue. Dual coil 10 wrap each, 3mm bit, 24g Ni200, set at 400 degrees and 80 Watts. Some times it works and works well. And then out of no where it stops working, I get the ---F no temp read out and it seems to be pushing straight power to the Ni200 coils. If I sit there and hold the fire button it will fire until the juice is all gone the coils go red hot and literally burst into flames. The last time this happen I decided to build new coils. These new coils id have set up nearly the same way. Instead of ---F Id get a reading of 2000+ degrees and then it would stop firing for being over temp. After a few times firing it the temp reading would then go back to ---F and start firing straight power to the Ni200 coils. Mod: Reuleaux DNA200 Atti: CCI Archon Coil wire: Ni200 from Lightningvapes
