Ceiling extractor fan

Refer to section 2.5

But most likely it'll be a zip-tie. It could be a large 'jubilee' clip, but most likely a zippie.

(You can make a big zip-tie by connecting a few smaller ones together - it works just the same.)

If you remove the fan, I would look at thoroughly cleaning it first.

If you can get access to the motor spindle as it disappears into the motor housing, then spray-PTFE lubricant is great stuff.

Sorry I missed that part 😄 

If I unscrew from the ceiling is there normally enough ducting to pull it through and connect the new fan? Otherwise I have to do it from above?

Usually there's enough - it's pretty flexible/concertina'd stuff.

How would you get to above this area - is it fairly easy? You shouldn't have to, but just in case the ducting falls away up 'there', and you can't reach it!

Somewhere on that circuit should be an isolating switch - it often looks like a light switch but the rocker switch part is stupid-wide. Do you know where it is? You need to find this, as it should isolate the power to the fan. Bear in mind that this fan will almost certainly have a LIVE supply even when it's turned off - it's for the timer or humidity overrun. So DO find that switch, but also flick off the appropriate breaker in your CU.

If the current ducting is held on by a tie-wrap, it'll need snipping off - they are not designed to be undone (tho' it's possible).
