Re: Long way around the barn!
Possibly due to a previous occupant playing around with the plugs and sockets to keep something running when the lights are off, leaving the fridge in the wrong type of socket.
I once had a room with such a mis-wiring. It ended up with a fridge that was turned on and off by one of the light switches beside the bed due to being plugged into a socket designed for the standard lamp beside it.
As the temperature outside was in the high 30's it got re-arranged so the bottles of water in the fridge were nicely chilled for rehydration after a long day at work (before being topped up with a beer or few).
