Ploom really needs to resolve these issues. My unit has the temp light problem all the time. And I clean it really, really well. I don't bother to send it back, because I am 100% sure it's the design of the unit that is it's own downfall. It's not broken, it's designed poorly. Or should I say, not poorly, just over complicated.
I don't know where you got your Pax from, but VapeWorld sent me a free MP when I started having those issues (which was less than a week from when I got it). I've had the new one for almost three weeks now, and it is much less problematic than my first one. It's just my experience, but maybe a new MP would help you too.
