What I found realy whacky was that we had to apply some heat to our spare fridge/freezer for the freezer to work properly. It is in an unheated outbuilding and when the temperature dropped during the winter things began to defrost. We were recommended to put a little frost protection type heater in and bingo - works fine. Apparanly when the outside temp was too low the freezer thinks it has nothing to do so it goes on strike!
