I have had a chattering noise coming from my timer unit and the display light was going on/off rapidly. I powered the oven OFF overnight to be on the cautious side, and when I powered up again in the morning it works ok and so do both the ovens and hotplates. I am a bit concerned though and would like to check for any loose wiring around the timer unit. How do I access the timer unit. regards Arthur (arthurlakin@tiscali.co.uk)
