The oven and grill are not working.
The overheat protection has lost a connector
and the connecting plastic connector covers were both charred 
The hobs are all working.
When the overheat protection thermostat is bypassed the grill works fine. The oven heats up, though current to the oven cuts out when turned to above 50oC
What I would like some help with is identifying which parts need replacing.
From what I have read I believe the oven termostat needs replacing though I am wondering if the 6 way selector also needs replacing?
Thanks in advance for looking
