  The fan run on you refer to is not this circulation fan at the back of the oven but a larger 'tangential fan' used to cool the controls and remove excess heat. This is usually controlled by a thermostatic switch that will only come on when warm (ie not if turned on for 2 mins) and will stay running until the temperature inside reduces.
