mwilliams Posted November 30, 2011 Report Share Posted November 30, 2011 Hi. My old timer bathroom extractor fan died, I could see a burn mark on the circuit board. I bought a new one and wired it up brown- live, blue - neutral and black - switch live. But it doesn't work when I put the mains electricity/ bathroom light back on. i've tested the brown wire with a voltage testing screwdriver and it lights up. Any ideas? Is there a fuse somewhere I don't know about?It would be gratefully appreciated. Mark Link to comment Share on other sites More sharing options...

mwilliams Posted December 6, 2011 Author Report Share Posted December 6, 2011 and here's a picright, thanks all for previous comments. I checked the wires with a multimeter and i have the fan wired up as follows: Blue - Neutral Black - Switch Live Brown - Permananet live the fan now works but only on it's timer circuit when i turn the bathroom light off. It's supposed to turn on when i turn the bathroom light on. I've tried switching the black and brown wires but it gives the same result. Any ideas?
