The problem is that I don't know what's causing it to short too.
You'd think that the coil staying in the chimney wouldn't be that big of a problem because you can just unscrew it, but every time I unscrew it I
throw it in the base just to check it on my DNA30 and it says shorted. When I look down into the coil head I can see the vertical coil isn't straight up and down, it's diagonal a little bit. I have no idea what's causing it to do that though.
This was never an issue before, but now every coil head that gets stuck in the chimney ends up being shorted. I don't know if I have a bad one or what's going on.
