Is this a range style cooker?
If so then the fault will be the oven selector switch that you turn. This s a very common issue on these as the switch burns out so sometimes you can get the red light fliker as you turn the dial.
On this to access the switch you need to remove the complete hob top and the front control panel.
From there you will see the oven selector swicth. Check this and you will find its burnt out. Now most of the time it burns the wiring as well so you will need to also repair the wiring as well on this before fitting the switch. So take a picture of the wiring first so you know how it goes.
So try the above if you are able to but from the fault you describe this is going to be the oven selector switch has burnt out.
If you need anymore info just get back to me.
No worries, I will await to hear from you.
No worries. Its always the back section that burns out on these.
So fingers crossed this will sort it from there.
