Hi Gillylily, I don't have one but I did look on line and found this : http://www.fixya.com/support/t3041496-am_getting_flashing_message_e5_temp They answered a similar question by saying it meant that the temperature dropped by more than 12 degrees. I read somewhere else that after the door was shut for awhile and the temperature returned to where it should be the code went away. Hope this is the case for you. Tracy

A cooler cools, but not really cold enough for beer and soft drinks. They are designed to just cool things down, like wine. If you want something that will really chill down other beverages, you will need a refrigerator instead. The cost is WAY higher, but it's because they have actual refrigeration capability and not just cooling.

You could always choose a refrigeration drawer with a storage drawer below it.

The IT person in me says this is a security problem, so you need to first identify your threat model. In a best case scenario, you can trust your kids and you teach them to treat alcohol with the appropriate respect; but you also avoid any taboo around it. This probably involves going ahead with a good example (i.e. drink responsibly and don't get drunk) and also letting them taste from your drinks when you have some. If you generally think you can trust them, but you are not 100% certain, then maybe all you need is an alarm system that tells you when it was tripped. Sticking a magnetic sensor onto the door and hooking it up to some sort of alarm system would achieve this goal. There are plenty of different ways of doing this. A quick search finds: https://smile.amazon.com/dp/B085HTMGYV combined with https://smile.amazon.com/dp/B07TQLKQLJ. I have not used this product before, but I think it could be set up to send you a text message whenever somebody opens the fridge door. Or maybe, you actually want to lock the fridge, because an alarm isn't good enough. In that case, the easiest option would be buying a panel-ready fridge and asking your contractor to attach a lock to the panel. A lockable door hasp latch would be the easiest option. But I am sure a good locksmith could construct a prettier solution. Finally, all of this assumes that your kids are at least somewhat trustworthy. If that isn't the case, things get much more difficult. All of the options that I quoted can be defeated: https://www.youtube.com/channel/UCm9K6rby98W8JigLoZOh6FQ When I was a teenager, I wasn't tempted by my parents' booze; but I absolutely would consider any of these security products as a worthy challenge.
