Product review (1 stars): This is not worth the time money.
Definitely trouble.

Digital screen shuts off when I run 2 burners.  When stove top cools it comes back on.
Latest problem is the oven door locked shut and won't unlock.  This is a safety option for the self cleaning function.
I was not using the self cleaning option and the door locked on its own then the screen read lock error.

The next  problem is that the screws that need to be removed to get to the failed part are behind the door that is locked.
