Bathroom Extractor Fan Install

[RT1187]

Isn't the pull cord on the ceiling your shower isolator? If so, does it also control your fan? If so then I wonder if it is fused down anywhere?

Yea the one on the ceiling is the isolator, I have never turned it off. But also the old fan had a built in chord which I would switch on when I hop in the shower to start expelling straight away. It would also come on by itself if it detected any humidity.

I'm guessing if I get a fan with no switch on the unit then it will just always run unless I turn it off at the isolator?

It's unlikely that the pull cord on the ceiling will be connected to your fan, but it's possible.

The ceiling isolator should only ever be used if any maintenance work is being carried out, and should not be used as a general on/off switch for anything.

I'd get a replacement fan which has a built in pull cord. 12V ideally to save having to worry about removing the transformer.

Thanks, I'll have a look for one.

I'm not sure what the pull cord on the ceiling is for then, I figured that as it's literally about 6 inches through a wall from the fan switch and transformer in the cupboard that it'd be part of that system.

Do you have an electric shower? Or did there used to be one?

It is an electric shower. It's a bungalow with a walk in wet room, used to be an old ladies house.

Yeah the isolator will be for that.

This is so much more complicated than it should be.

I ordered a 12V fan this morning with pull cord from Amazon, it just showed up and it has no pull cord or on/off switch at all. I am right in thinking if I install it it will just continuously run as it isn't connected to the light switch or anything? The wiring at the hole for the fan is just a blue/brown wire which I assume is just neutral/live?

I'm struggling to find a 12V Fan with pull cord anywhere, I'm not sure how the timer models work exactly but would that be a solution?

A couple of things to throw in the mix-

Do you know whether the transformer for the fan is 12V AC or 12V DC?

Do you know if the transformer actually works?

I'm really not sure how to check this.

The old fan was 12V so I'm guessing the transformer was working?
