Bathroom extractor fan not working

[EFLImpudence]

What is the terminal block ?

The connector with the black and other blue wires.

Im not an electrician so terminology is beyond me and would that be the case if all the lights in the bathroom and hall are working fine ?

If the switch in question only operates the fan, then yes.




Having just read your latest post we can only say that you need an electrician who knows what he is doing.

Ok lol.
The guy I had out this morning, I'm guessing, knew less than me.
Just one last thing. If the old switch had a port for neutral which I'm sure it did but this new switch didn't then could it be the switch thats at fault ?

You have to choose between Plan A and Plan B.

PLAN A:

• Learn how lighting circuits are wired.
  • //www.diynot.com/wiki/Electrics:Lighting
  • http://wiki.diyfaq.org.uk/index.php/House_Wiring_for_Beginners#Lighting
    
  • http://www.google.co.uk/search?q=uk+lighting+wiring+(basics+OR+101)
  • //www.diynot.com/wiki/Electrics:books
  • //www.diynot.com/wiki/Electrics:index
• Get a multimeter and learn how to use it.
• Identify which conductors are which at the switches and the light positions.
• Work out what should go where and connect everything up properly.

PLAN B:

• Get an electrician.

There are some irresponsible people here who will tell you that there is a Plan C, which is to start trying different things without really knowing what's going on, hoping to get it working by luck, or by blindly following instructions to put-this-wire-in-that-hole without any idea as to why. Please don't listen to them - you must know what, and truly understand what, you are doing.

Electrical-installation-by-guesswork is a foolish idea.

There is no Plan C for anybody sensible.

Thanks for all the help.

Just to point out that -

some switches do have a terminal for the neutral wires but it is just a parking place with no connection to the switch working.

Having only one wire in this neutral terminal would do nothing and affect nothing else.

I would expect the red to the bathroom light and the yellow to the fan to be in the same terminal.

Thanks for the extra pics, having studied them the switch wiring looks ok apart from one cable being in the wrong connection, as mentioned by sparkwright. Please be advised that this is pure guess work on my part and i echo the comments that you are best calling in an electrician to safely resolve the issue and tidy up the messy switch wiring. Out of interest are you able to take a picture of the wiring connections on the fan itself? Even with the cable in the wrong place i would expect the fan to come on when you switch off the bathroom lights so there may be an issue with the fan wiring too.

Unless it's a DP switch

I'll stand on the last line.

nice to see the cables have been tagged, good electrician ?. I think not

They were never tagged to begin with.
