Bosch single oven with delayed timing

[Myfuchia]

Last week I had the above fitted and I find when the oven had the delayed timer set a fan inside the oven starts. I've contacted Bosch and they say this is ok. My electrician phone them and spoke to the technical dept who say its new legislation to protect the food in the oven before it starts cooking. I disagree as its using power for no reason. Has anyone else found this problem

I don't see how a fan will 'protect' food. It will just blow more germs across it and dry it out.

I can't find any legislation on ovens except for the rating model etc. I've never known a fan running at the setting point. I think this oven has to go back

Ok thanks for the update.

Is it the main fan... In the middle of the back 'wall'?? Or another fan somewhere?

As our Neff has a small fan that starts up when in delay start mode.

It's not the main fan, seems more like one fitted to cool the control area after oven is turned off or something..

Definitely can t see the main one on the back spinning, but there is something blowing gently.

ETA...
It does the same on both the single oven, and the double.

Why is air blowing out of the top of the oven door?
Don’t panic! This is totally normal. The cooling fan inside the oven is in operation and works to blow air out through the vent at the top of your oven door, just below the control panel. This is an important function that keeps the control panel cool to the touch, preventing the cook from burning their fingers when altering the controls during cooking.

Cooling Ventilation
In order to cool down the external temperature of the oven, some models are fitted with a cooling fan that blows out air between the control panel and the oven door.

This is the cooling/vent fan running and not the cooking fan motor.
There is a vent in the roof of the oven cavity that passes into the airflow produced by this fan.

Not a fault.

I think the case fan running when on delay start is a fairly new thing - I've seen it mentioned before, but certainly our oldish Neff doesn't do it, the case fan only come on a couple of minutes after the oven starts to warm up.

Have you read the instruction manual or Googled this for a technical bulletin? BTW, if Bosch themselves say it's OK, then I'd guess it's OK? (Power use for fan only would be minimal)

I can’t remember exactly when this came in, but have seen it on (BSH) ovens for several years now. As mentioned the fan motor is likely to be only about 20 watts.
