OK , it sounds like the fan has gone and needs replacing , if you have a voltage tester or electrical multi Meter you could confirm this by seeing if it has any voltage , if you don't then I would replace the fan, if there wasn't voltage to the fan then it could be the PCB at fault
OK , no probs was going to recommend a good place that does reconditioned parts for half the price but you have to take the old one in . If you can get hold of a voltage tester though ( can get them for less than ten pounds) just to confirm you have power going to the fan and its not running, with a voltage tester you only need to touch it to the wires and it lights up if electricity is running through . if not you could just get a new one .
