Hi,

I have a hood type extractor fan over my hob. Lately this has given up on
its extracting duties. When I turn it on theres the usual whizzing noises
but no air is being sucked up into the hood. I took the cover off the hood
and removed the filter (pretty clean). There's a big fan that spins round at
an impressive rate but I can't feel any updraught of air into it. I climbed
on to the kitchen roof and checked that the vents are clear and you can feel
a slight draught coming from the vent.

Any clues?
