Well, after a bit of a faff (cap didn't arrive) I ordered another from
elsewhere, put it on and nothing. ;-(

The fan still 'hums' slightly when power is applied, like a coil is
getting power but the motor not spinning?

The strange thing is previously, if the fan left (for say a couple of
days) and you turned it back on again it would actually spin up ...
but then slowly slow down and stop again.

Strange ...


Have you stripped the fan and oiled the sintered bearings?

No, no need, the fan blade spins very freely and the whole thing looks
like new?
