Red has you covered real good.
That Gen #2 is a problem child.
I never had that flare-up stuff with my Gen #1 MES, but if I did, I'd be afraid to leave it alone.
If it's too late to take it back, the best thing for you to do is get an AMNPS, so at least you don't have to fight with the chip burner in that thing.
Also don't trust the temp readings either----Think about getting a pair of Digital wireless therms, so you'll know what the temps really are.
Thanks for the advise Bearcarver. Perhaps getting the AMNPS is the way to go.
