I've got two of the Nuwave induction burners here at the manse. I use them almost every night. Sometimes if I cleaning or whatever, I will put one on top of the other and being a lazy slug just use the top one. WELL, lemme tell ya, plugged the top one in and started some green beans. Went to fix another adult beverage and was hearing something odd. Walked back into kitchen and the bottom UNPLUGGED burner was beeping, all the light were flashing and it was making some other weird noises. Immediately unplugged the top burner, seperated them and tested both. No problems with either. Random event or should I cancel the in ground pool install for fear of caskets popping up?
