Ok so extractor fan in bathroom was working all of a sudden all the lights and extractor fan go off, go to fuse box turn themback on but fans not working. Any help on what this my be and how to fix I would be extremely grateful. The fan is quite a powerful one from memory and it turns on with the lights as long as the fan switch is also turned on as well. So basically outside the bathroom theres a fan switch on/off and light switch. The Fan switch does not have a section in the front to remove a fuse. Any help gratefully received.
