I have a Zanussi ZFC56/38FF and the fridge section is now not cooling even though the freezer section is. Can anyone advise of what the problem might be? Everything still sounds as if it is working.
You’ve probably got an ice build up in the freezer restricting the air flow to the fridge.
Try a 48 hour defrost to see if that helps, if it does then that will be the problem but it may not resolve it totally as a component failure may be causing the ice to build up.
