I have an EA Mod which works well. I use AW IMR bats. All my bats are new (bought within the last month). I'm generally using the mod for genesis vaping. I have several AGA-T2 tanks. I use 500 mesh, 28g kanthal, and wrap 1ohm coils without issue. My issue is this: From time to time the fire button gets hot. Hotter than it should. I'm not chain vaping and can vape pretty consistently without feeling excessive warmth from the button. Then, out of nowhere, the button will start emanating heat. I'll check the atty for hot spots or hot leads and they look fine. The vape tastes fine. The resistance checks out fine without fluctuations. The battery doesn't get hot, just the fire button (and I suspect the battery post). Once this symptom starts, it continues no matter what (low resistance coil) I put on it. The post and pin are brass and clean. I did noalox the telescoping threads as well as the end cap threads of the mod but there is none on the positive pin. I used very little, but perhaps I should not have used any. I removed the button and soaked it in rubbing alcohol to clean it which helped for about a day but the heat problem came back. I can switch three different known working gennies, all in the 1-1.2ohm range, and they all make the button hot so I don't think there's a short in the coil end. Also, I have tested this with different batteries, with a Vape Safe fuse and without, all with the same result. What are your experiences with these type mods and what do I do to check, troubleshoot further, and fix this issue.
