Hi all,
I've had a look at similar threads and a couple of YouTube videos but still stumped I'm afraid.
Need to replace the bathroom extractor fan (it works but it's incredibly noisy and clicks loudly), so I removed it and the wiring was connected in two places, in the two "groups" consisting of 2x red and 1x brown each as shown in the pic below (n.b.: I added the silver tape when removing the fan so I could differentiate the two groups). I've not seen this combo before.
These were connected into a block, which then met up with the black and the brown wires in the ceiling. There's also a grey one not connected to anything (neutral, I believe?) and Earth also not connected up (but we have an isolation switch on the wall specifically for the fan).
The new fan has terminals for L, S/L and N. I've tried it with brown in the L and black in the S/L and vice versa, and both with and without the grey into the neutral. Can't get a bean out of it. I even took it back to Screwfix and replaced it in case the unit was DoA, but same issue again.
If it's any help, the fan always comes on with the light and goes off as soon as the light is turned off.
Is this a "get a multimeter and/or sparky" situation, or can anyone think of anything stunningly obvious I've missed?
Many thanks in advance
Matt
