Question, regarding optical sensors used in K3

[NK7Z]

Hi,

I had an occurrence where one of my smaller knobs, (Filter Width),
became erratic in its control of the actual filter width...  Skipping,
and not having any effect at all...

I fussed with it a bit, and now it is working...  Is this a sign of
imminent failure or is it just a bot of dirt?  Any way to tell?

I hesitate to bring up the obvious, but are you certain that it isn't
simply slipping on the shaft?
