We have a fridge with a third drawer that can be configured as either 'fridge' or 'freezer'. It has a 'Lock' to prevent the configuration from being changed accidentally. We had ours set (and locked) to be in 'freezer' mode. Yesterday, we turned off the electricity for a few moments to do some work. Later that day, I felt some frozen bread in that drawer and discovered that it was starting to thaw. By turning off the electricity, we had reset the mode to 'fridge', even though all of the other temperature settings in the fridge maintained their previous configuration. Why did all of the other settings remain, but that one didn't? Such annoying technology.
