Oven working fine then suddenly in the middle of cooking the oven started making and breaking the electrical circuit.
– you can here the switching on and off of the circuit – from the front you can see the clock switching off and on intermittantly – there appears to be no problem with the power cable
Have you checked the terminals at both ends, power off at fuse box feed.
If all that is fine you have checked as much as you can I think.
Try the link below for an engineer.
Not checked much still under warrenty – but you were spot on with the connection – I found the live feed from the mains sput had come loose.
big thanks
