My fridge and freezer makes noise to the point that it is hard for me to sleep (even with earplugs) so I have began to shut off the power to the fridge and freezer during the night. My fridge is set to 1 degree celsius and my freezer is set to -18 degrees celsius.
When I go to sleep I move all the fridge items such as milk, cheese, butter, meat, kefir to the freezer and shut the power off for 9-12 hours when I sleep. When I wake up again, I turn the power back on, wait about an hour or so and put my items back in the fridge. The freezer temperature when I turn the power back on is around 3-4 degrees.
I don't feel ill when I eat the food, all I have noticed is ice crystals in the milk and that the cheese is a bit harder to slice. I am wondering about the long term effects of this process, both the food safety aspect and the quality of the foods. Is there any food items that are less safe to do it with?
