I've got a cooker hood, something similar to
http://www.baumatic.co.uk/products/c...rhoods/F70.2SS that
has recently started turning itself off after about 5 minutes use,
then coming back on again a bit later. I assume it's some kind of
thermal cutout mechanism like eg a hairdryer has.

I've cleaned the filters (it's ducted outside, so I'm not using the
carbon recirculation filters) and checked that the fan itself seems to
run freely, which it does.

Any ideas what could cause this? I don't mind taking it apart and
cleaning/replacing anything, but I don't really know what to look
for... I wonder if anyone has had this problem before?

I dont know either - is the motor covered with insulating muck? Does
it only do this on the max speed setting, or on all? (Only on max
might suggest a partial short)

Thanks for the reply and good question - it has 3 levels, I usually
use it on max no 3. It seems to run fine on no 2 for as long as I like
- then when I turn it up to 3 and it turns off after about 2 mins,
until such time as it (presumably) cools down and then starts again.

Any ideas? It would be a major PITA to have to replace it

I'd be surprised if it has. A hairdrier or fan heater has an obvious need
for one - but a plain fan not. More likely to be protected by a thermal
fuse in the windings.

Page 23 of the instruction manual (linked from above) says that if it
stops during operation, the safety cutout has probably tripped...

Doesnt it move enough air left on 2?

Ah. Right. Sounds like they've economised on the motor rating.
