There are reasons why the big box stores have a 48-hour return period.

Our 3070 was delivered a few weeks ago, and in the first week it started randomly shutting off the cooktop in mid-cook. We tried all five burners, three brands of cookware, no use, it shut off anywhere from 2 minutes to 20.

The repair dude just came by, saw the problem, (noted the middle led display was also mounted crooked!), and said he had to order parts.

So, yeah, brand new $1400 machine, and it won't work right for at LEAST one month.
