Hi,
I'm trying to replace an old extractor fan in my bathroom which has blown a switch, so I've bought a new one.
The replacement one I've bought is for use with a 2 core flex.
My old one had a 3 core flex (ie. spot for L, N and L1).
Only problem is I have two separate flexes to chose from.
- Flex #1: The first flex has a black wire, a red wire and an earth.
- Flex #2: The second flex has a blue wire, a red wire, an earth, and a yellow (but with red about it).
The two earth wires have been separately isolated.
I originally put the blue and black into the N, then the two reds into the L, but the fan kept going even though the light had been off for abour 2 hours! That left a yellow wire (which had a bit of red around it as well so identify it as a red I think), which I left off to the side.
I then put the yellow wire (with the red bit around it), into L with the other two red wires. Same thing happened, the fan didn't go off even after the light was off.
I then have tried different the following combinations:
1. Black from Flex One in N, with Red from Flex Two in L
2. Black from Flex One in N, with Red from Flex One in L.
3. Blue from Flex Two in N, with Red from Flex Two in L.
4. Blue from Flex Two in N, with red from Flex One in L.
5. Black from Flex One and Blue from Flex Two in N, then Red from Flex Two in L.
6. Black from Flex One in N, with Red from Flex One and Red from Flex Two in L.
7. Blue from Flex Two in N, with Red from Flex One and Red from Flex Two in L.
I don't seem to be having any luck.
Can someone please please please help me!
Have I got this wrong because I have the wrong type of fan (ie. its a Marley Basic model for use with 2 core flex). Do I need a fan with a 3 core flex instead?
Alternatively, have I got this wrong because of my wiring?
