Any suggestions anyone please?............
I had an extractor fan installed 4 years ago in a new downstairs loo. It was a timer fan which came on with the light switch. It worked fine for 4 years then broke, so I bought a new timer fan which I assumed would be a straight swop - I installed it and it doesn't work. I'm not an electrician, but I have put in a few timer fans over the years with no problem.
So I have checked the supplies to the fan with a multimeter and I have power to the switched live when the light is on (as would be expected), however there is zero voltage at the permanent live supply. If I turn off the light I then have power at the permanent live. Surely the permanent live should always have power? As I said the old fan was quite happy with this arrangement, but the new one isn't!
Can anyone explain this or suggest how this can be sorted out? I have talked to the electrician who did the initial installation - but he is too busy to come right now to look at it.
