    Hi All,

    I have a Silavent 354511 model extractor fan fitted in a flat (probably about 15 years old, when
    flats were orginally built). It's on a pull-cord, and comes on okay, but won't turn off
    at all when the light is turned off. So, I opened it up, and set the timing mechanism to
    the minimun of 1 min, and lo and behold it turned off after about a minute. But when I put the
    cover and casing back on, and screwed it back to the ceiling, it stopped turning itself off
    at all. I tried this a few times, and each time, I managed to get it to turn off after a minute
    when it's out of the housing, and hanging loose on the cieling, but everytime I put it all
    back together, it carrys on running and running.

    I find this most peculiar. At one time it did run at all, and I messed about with it, and then
    it came on. I can't replace is easily, as the housing where the fan goes is much larger than the
    fans which we buy these days from DIY store. The silvent.co.uk web-site no longer lists this model.

    Any thoughts? Ideas?

    I think 15 years is pretty good going for an extractor fan!!

    Post a picture of it and someone might know of a similar sized model..

    Have you had it off? (THE FAN I MEAN!!)

    Look here for a replacement, or ring them up with your dilemma.

    I've seen Silavent Mayfair Classic's last more than 20 years (well not seen them start to finish at my tender age but good reason to believe they are 20yrs+), well worth it at £100 odd a pop.

    To the OP, strange that it works while hanging out, sounds like it could be some kind of short between the live and switched live, worth checking for damage to all visible wiring (with power OFF)
