I have a whirlpool american fridge/freezer which is now 3 months out of warranty and just developed a fault. The fridge and freezer have stopped getting cold but the display says all is fine -18 for the freezer +4 for the fridge . I first noticed that the ice cubes were melting, so i checked the food and sure enough the frozen food on the top couple of shelves was getting soft , i removed all the food . It will not make ice cubes either , but the back wall of the freezer unit is icing over quite badly which it has never done before. There are no red lights or anything flashing on the display panel. The motor still seems to run ok , this can be heard.
Any suggestions ???
