Bathroom Extractor Fan Problem...

Westward10,

Rest assured I used the diagram for layout purposes only, not for material guidance...

definitely an improvement. personally i'prefer wago boxes and connectors.so much more versatile. the connectors are push in, no screws to fart about with.

Niiiice!! Do they do them small enough to mount on a joist? Kinda restricted on space which is why I used the J-Boxes in the pics.

 

[westward10]

Agreed it is an improvement.

 

[telectrix]

they do smaller ones, but you need to consider how many cables/joints are going in it. the one i linked is only 120 x 115 ( milli thingies, not inches which is what i understand). don't matter if it overhangs a bit if you'r e not boarding.

Anyway, pulling the thread back on target... ;-)

So, in summary:
1. Wired as per fan terminal labels it runs constantly, no switch control.
2. Reversing L & SL gives switch control but no timer.
3. My J-Box husbandry requires attention.
4. CPC has no effect on my fan defect.

If so, I therefore need to call the manufacturer and ask them:
1. Why is the L/SL labelled incorrectly?
2. How exactly do you activate the timer on the fan (as the instructions do not say).

Best regards,

Thanks Telectrix.

If you have a multimeter test between the line (brown) and neutral (grey) with the light switch on and switch line (black) and neutral at the fan. You should get 230v with both of them. Turn the light switch off. The switch line will be dead and you should still have 230v between the brown and neutral.
If that is the case then it has to be a faulty fan.

Thanks Lee42.

Kids are in bed now so stumbling around in the loft will have to wait until the morning.

However, even before I put a multimeter on it have I not already proved both line and switched line voltages? If wired as per the installation diagram and fan labels, the fan runs constantly as soon as the CU is turned on, regardless of light switch position and/or if I operate the light switch (so line voltage must be present). But at the same time the lights turn on and off as commanded with the same light switch (therefore switched line voltage must also be available).

The more I look at it the more it seems like a fault with the fan. But for it to be happening with both supplied fans seems rather strange...

didn't realise they had bathrooms in Luton. thought it were outside bog and a tin tub hanging on a nail between saturdays.

Oooh, Scouser got jokes... PMSL!!

I'm actually a displaced Essex Boy, but regardless, you seem to have us all confused with Yorkshire...

 

[telectrix]

essex? that's even worse. they bathe in the estuary there. it's the floating turds from london sewers give then the fake tans.

 

[Billy Whizz]

Nice! But the turds are brown, fake tan is orange...

Why on earth have to gone to Luton.

Its not something straight forward like the over run timer set to max. Some fans can over run for along time.
