Is it just one ring thats comming on on its own?
If so which one is it?
Thanks for that.
If its just the 1 ring comming on and it comes on as soon as you turn the cooker switch on then the fault will be the hob regualtor. This is the switch itself for that ring. To fix this you need to replace the hob switch for the front right element and that will cure the fault and stop it comming on all the time.
If you need anymore info just get back to me.
