New bathroom fan issue

[Andrew777]

Recently the extractor fan in my bathroom stopped working properly after more than 10 years (it was making a whining noise/sounded like it was wearing out) so I bought exactly the same model to replace it.

I swapped the fans over - putting the live and neutral wires in the same terminals as the previous fan. However when I turned the power on the fan did not work. I thought that the new fan may be faulty so I took it back and got a replacement (same model). The same thing happened - no power. I ended up exchanging the fan 3 more times (the last time I bought a different model), but the same thing happens each time.

I have tried attaching a standard light bulb to the wires which works OK, (see pic).

The models of the fans i have tried are:

Any help would be appeciated.

Did your original fan have a timer ,so it would continue to run for a while after you switched it off ?
Your pic appears to show only two conductors ( live and neutral ) ,and the fans linked are fans with timers ,that would need 3 conductors , permanent live ,neutral and switched live.

The old fan had the option of bypassing the timer (which I did), so I was only using the same two wires you can see in the pic.

Connect the live to both live and switched live.

Timer won't work but the fan will.

Do the fans you tried also have the same facility ?

 

[Andrew777]

Yes, they were exactly the same model.

Connect the live to both live and switched live.

Timer won't work but the fan will.

I will try this - Thank you.
