Not sure if this will help but I just fixed the temperature and function indicator on my Smeg A1-6.
Turn off the cooker at the fuse box. Turn off the cooker at the wall. Can't be too careful here :-)
I removed all the knob and timer buttons by simply pulling them gently away from the over. With this done I unscrewed the metal plate (where the knob and temperature indicator reside).
With this done all I had to do in my case was to push the connections firmly back in place. If not you now have access to the parts which you can then identify and obtain replacements.
Reassembly is simply the above in reverse.
Good luck
