Hi all, I have got a second-hand fridge/freezer which isn’t cooling the fridge properly. It is a Beko CGA 966. The freezer and bottom half of the fridge is fine but the top of the fridge is a lot warmer. I have read somewhere that it could be the fan but I have no idea where the fan is located as it doesn’t tell you in the instruction manual. Any ideas would be appreciated. Thanks!
