UPDATE: Hi, I turned off the freezer and left it open for a some time and turned it on and left it empty before going to sleep. When I woke up temperatures of Freezer and the fridge were both right. Thanks a lot for your help guys!
I removed all the stuff from the fridge and put it in the freezer, turned off the fridge, and left the freezer on. Will that work? I really don’t want all the stuff to go bad.
