My Cannon Chichester gas cooker has a minute timer with a warning "bell" which works fine when cooking for short periods but won't sound at high temperatures when the cooker has be in use for quite long periods. I can only guess that it is failing when it gets to a certain temperature. I would like to access the mechanism to see if cleaning it would help, but don't know how. Has anyone any hints & tips on dismantling?
Thanks in anticipation.
