Zannussi ZFC56/38FF Fridge not cooling.

Very Very Gratefull thanks for the suggestions I have read on the Forum re my make and model of Fridge-Freezer. I used a suggestion, turned the F/F off and unscrewed the back plate in the freezer (5 Screws), it was badly iced up although the fan etc was working fine, I hairdryered it, and now all seems to be working well. Thanks so much ‘Dave’, I am a single parent and the thought of a call out fee and repairs 4 days before the first holiday in 3 years was worrying me dreadfully. What a good forum this is I will be recommending it to my friends and family.
