Replace existing 4 inch centrifugal extractor fan in loft

[ernest1990]

Hi my 4 inch centrifugal extractor fan in the loft has stopped working.

Looking at doing a like for like replacement, but am confused with existing wiring vs wiring on the new unit and where the current wires would fit into the new unit.

I've attached the current wiring set up for the broken one, (first image) and then a photo of the new unit (second image).

Thanks,
Andy.

Check the instructions with the new fan, but your old L and SL (switched L) will be L1 and L2 (or vice versa).
And N will be N.

The new fan L1 is damaged by the screw, and needs correcting before you connect it up.

New fan might just be a two speed one, without an over run timer, in which case you've bought the wrong type.
There's a couple of points with the original wiring that raises red flags. Needs a professional check over.
