I've got a couple of these mods and they are some of my favorites. Lately, one of them has been throwing a Device Too Hot error. The mod won't do anything when this comes on; I can't even turn it off when it is there. I let it sit for a couple hours and it goes away for awhile and it works well. I have googled this and it seems to be a common problem but I haven't found an answer to the problem. I'm going to take it apart soon and clean up everything inside because I suspect it's a problem with juice getting in. Anyone else had this happen? And if so, what did you do about it?
