Ok, so yes it’s definitely set to tru fan oven the picture of a fan with a circle around it.
I have taken the backplate off and the fan is spinning and the element is getting warm but not anywhere near glowing red.
The resistance of the element (disconnected from wires) is 72 Ohms and it is a 2400W element. By my calculation this should be 22 Ohms so a 72 Ohm element would only produce 734W .
Is my reasoning correct? Seems like a new element is required although not sure why it would be a bit higher resistance unless of course it’s always been rubbish due to a faulty manufacture.
