When oven switched on the element is glowing red as normal, reaching temp at usual speed. It then switches itself off after several minutes and stays off. However if I open oven door it will switch itself back on, but then turn itself off again after several minutes
It comes on after a few minutes i.e. I guess once the oven has cooled down a bit. We close door again and element turns off after a few mins. I am not sure but I presume with door shut, element will come on again after a longer wait while once oven cools right down again.
I think the oven reaches the correct temperature at the start, but then does not sustain because it turns itself off .
I'll see if oven turns itself on and off repeatedly with door shut.
I agree door has nothing to do with it - the oven just cools faster with it open so that the element can restart again sooner.
If this is not the case can I come back to you?
