Because I live in a former eastern bloc country (Hungary). My only guess is the fridge is that old. (It's not mine, but it came with the apartment I live in. The building I live in is Russian built too. :)

I will look again it, to make sure I got the letters right and to make sure it is pointing at what I thought it was. Since my Russian is so bad, when i checked last time what the words said, I was repeating "V soft sign K L" to myself so i wouldnt forget it before i got back to the keyboard. (I was confident i could remember min and maks) so it may have stood out in my head enough that i forgot what it was set to.

But it's definitely cold in fridge, so it cannot be set to "turn off."

This time, I take my camera with me :)

.... and discover that it is set to maximum (МАКС).

Here is a picture http://pics.livejournal.com/pthalogreen/pic/0012rat7 . It also has another setting "НОРМ" which im going to assume is the "normal" or "medium" that i was remembering that it had. I think I set it to maks some time ago in attempt to solve the food spoilage problem.

It's really hard for me to remember выключить because my knowledge of Slavic languages (and understanding of Russian via cognates) comes mostly from southern slavic languages which I have studied, like Serbian, and uključiti in Serbian means "to turn on".
