Beomaster 5500 Master Control – rotary control only works in one direction

[dave_n_s]

After many years of faithful service, my master control panel only works in one direction (turning anti-clockwise).

I realise it’s optical, but that bit is clearly working, correct?

Any pointers on how to troubleshoot would be appreciated.

From memory there’s also a little microswitch* next to the optical sensor.  This is mechanically operated by the wheel and basically tells the system which way the wheel is turning.  I would look at that in the first instance.

(* as opposed to a ‘big’ microswitch 😀)

EDIT2:  This thread discusses the problem and has a useful photo of the switch:  https://archivedforum.beoworld.org/forums/t/35687.aspx
