A:AnswerGlass shelves, 1/4" thick. I put my items in individual bins and label the bins. I can move bins around on different shelves without relabeling the shelves.
A:AnswerTry unplugging the power from the unit and then replugging and see if the hi temp goes away. Could be the default after a previous power interruption.
Also, you can set the temp to what you need by pressing the + or - button - you may firs that to press the lock button for 3-4 seconds before it allows you to make changes. I have my freezer set to 0 deg F and fridge set to 39 deg F
