I have a zanussi under the counter fridge with small freezer which is in a flat I rent out. One tenant moves out and defrosts fridge prior to leaving and switches off. New tenant moves in, turns fridge on and everything in fridge now frozen solid. Setting is at 1. In middle of dial there is a red bar. I have pushed this in and also pulled it out. No difference. Can anyone please help.
Grateful thanks.
