    Anyone know how I can dismantle this hood? It has stopped extracting - only thing that works is the light and the pilot light for the first degree for extraction.

    I'd even be happy just to get it off the wall to enable me to install a new hood.

    Remove the screws on the lower cowling, it then should lift up a bit & can then be remove, it slides over the top section.
    The flexible vent pipe should pull out of the socket on the hood.
    There are two pozi screws on back of hood, visible in your link, which fixes hood to wall,remove them, then you can lift hood off the two supporting screws higher up the wall.

    See this link.

    The chimney cover may have been caulked to wall or plastered in so after removing screws, run a knife between cover and wall to free

    After removing, wall brackets will be visable and all will become apparent :)

    Thanks very much, comrades - you've given me the courage and confidence to tackle it now.

    In the meantime, if I prove to be successful in removing it, do you have any idea as to how to diagnose it?

    The most common failure of cooker hoods is the starter capacitor. They're really cheap if you buy them unbranded on eBay or Amazon. I recently got a quote for a starter capacitor from Elica for £26 + postage. I got an even better spec'ed generic one online for £2 including postage!

    Because starter capacitors are such a common failure component, it's worth mounting them 'externally' so they're easy to get to and replacement doesn't involve dismantling the whole hood, e.g. behind a panel or in the ducting housing. It does require extending the wire a bit, but that's only a one-off activity.

    Odd development - the fan which had been left at the on position - started working again of its own volition.

    I haven't been able to identify the maker of the hood - this is the only label on it:

    If the fan is now working, it's obviously not the starter capacitor.
    The fact that it started on its own now points to the switch. (Incidentally the switch is the second most common failure on hobs, as they tend to get a lot of muck in them from steam and grease.)
    If it were mine, I'd disassemble and clean out the switch, paying great attention to the contacts, which I'd clean with alcohol.
    From your video it appears that switch is relatively easy to get to now the filter is removed.

    I disassembled the switch and soaked its innards with alcohol for an hour. After letting it dry, there was no fan function at all.

    The pilot lights at setting 1, but tiny and dim at 2 and 3 - see video.
