Hi, could really do with some help with my extractor fan. The fan used to come on when turning the bathroom light and and then run on for about 5 minutes once light is turned off. The fan stopped working a few months ago and I'm trying to get it working again. I've checked with a multimeter that I'm getting 12v at the fan which I am and also checked to see if the transformer in the loft is sending 12v which it is ( I'm actually getting 13v). I've replaced fan and transformer still no joy, any suggestions?
