Thanks for all the helpful replies.
I got a call this morning saying the motor was still whirring but the
curtains now wouldn't open at all.
Will have to get over there and see if I can get inside it armed with
the info provided here.
IIRC the motor hangs down behind the curtain on a sort-of plastic
stem. I think the system must be about 10 years old, came from John
Lewis and wasn't particularly cheap. The fitters they sent hacked it
in to a circuit in the loft - I forget what particular mess they made
but it was something ridiculous like the curtains not working if the
wall lights were turned off at the main switch rather than the pull
cords.
Never been particularly impressed with it. When it works, it works
and it fulfils a need for an arthritic person with poor grip but the
design and robustness seem to be needlessly lacking.
