HI

I have just tried to replace an old ceiling fan with a ew one in my bathroom

When I unwired the old one it had red and black wires only

However when I put the new one into place it has 3 places to put wires

L,N,LS- I have tried all combinations of putting the two wires into it and still no life in the fan

Anyone got any suggestions?

Have you put a tester on the wires so you know which one is the neutral and which one is the switched power?

Go back and add your location to your profile.
And let the guys in on what L,N,LS is suppost to mean.

Doubt that....provide a photo of the wiring of old fan.


And while you're at it a photo of the ceiling box and the wiring of the new fan
Please see pictures I have

One of new fans connectors- picture is not great but you can see that the letters next to each connector- L, N and LS(Called new fan connectors)

Next picture is the new fan with the 2 wires that I have to connect it to which is what powered the other one (called new fan and my wires)

Final picture is the old fan which only had two connectors( called
old fan connector)

I am in the UK

Any help is appreciated

Added location but I dont know what L or N or LS mean
Educated Guess:

  • L = Line
  • N = Neutral
  • LS = Line Switched
Less educated guess: Assuming this is a 230V circuit, the two wires that used to connect to the old fan go to L and LS. Nothing goes to neutral. Just a guess.

Picture #2 partially shows a wiring diagram on the right hand side. Could you take a better pic of the diagram?

Thanks.

Now, to the left of 50Hz, there's a voltage specified. What is that number?

I know little of the history of electrical wiring in UK. Was there always a neutral line? I thought it was just two hots (+120 and -120). In other words, a pure 240V system like we in the US might use for a water heater.

response to joke advice

dont think there should be such thing as diy with electrics, as a time served electrician some of these suggestions are a joke, yea no neutral, your 2 wires to l and ls brilliant, as long as the shop you bought the fan from is still open to buy a replacement when you put a dead short across it . l is red/live n is black/neutral ls is live switch giving u the abillity to wire it off the light if u want switch facillity,put a link of cable between l and ls and your black is neutral, hope your fans still ok after the other suggestion.

That's a great reason not to try giving advice, even if you are "just trying to help". European voltage is a hot and a neutral, even though it is 230V. Depending on age, it may or may not be grounded.

Even worse is that in the UK, there are a lot of ring circuits.

Best thing to do IMHO is suggest they find a DIY forum in the UK.

I know someone mention my name here.,

So I am here.

to OP .,

Follow my instruction excatally the red is active while black is netural which we know that is old colour format and you will have to hook to L et N not the LS slot at all unless you have a take off spur or switch loop that the only time.

Is that old fan was controlled by wall switch point ?? If so follow my instruction excatally as I mention above.

Now for the rest of readers please advise this part is NOT a North Americian format for voltage level I know you say 230 or 240 volts but this is between line and netural just like your 120 volt system and I know UK do not have centre tapped transfomer system like what North americian use ( but they do have it but super limited useage )

And Please .,, Please respect this due the voltage and wiring methold is not the same as you guys are in North Americian side.

Merci,
Marc

P.S. Note that the methold what been used in UK do not follow the NEC or CEC ( Canada Electrical Code ) they have it own BS ( British Stanard ) regulations.
