ECB Tripped a few days ago, couldn’t pinpoint cause and didn’t reoccur. Have noticed aver last few days that Mistral (FF72) is showing what seems to be a standard problem of Freezer Ok (Fluctuating around -17 to -20), te fridge at room temperature (+20). Wondering of ECB trip releted to a failure on fridge. Fan runs Ok, all dust free, no frost, ducts seem clear. Any help gratefully received, as this has been a brilliant unit, and will be hard to replace.
