Zanussi fridge freezer was defrosted yesterday and not working since... it has power going to it, the light is on and i can hear the motor working etc But everything is warm in the fridge and the freezer feels a bit cool but nothing more... not freezing

Its an intergrated ff, when defrosted the power was just turned off and hot water in bowls letting the steam defrost the freezer.. have used this method loads of times

The Freezer was over freezing before this defrost, it was even causing the back panel of the fridge to freeze up... it did make funny noises for the past 12 months, like a bubbling noise. That bubbling noise has now stopped??? Any ideas what could be wrong, just dont have the money to go buy a new ff at the moment!
