Wall Mounted Electric Oven Vent/Blower

I have a Kenmore electric oven (wall mounted model 79047833405) with a vent located between the top of the door and the bottom of the control panel. There is a blower in the vent line that turns on anytime the oven is in use. The blower releases a significant volume of heated air to the kitchen during the whole heat-up/cool down process. This inturn increases the electrical demand on the over to maintain the desired oven temperature, increases the demand on the air conditioner, especially in the hot summer months (like now), and tends to raise the temperature of the kitchen, making it more uncomfortable to work in. The owners manual says that the vent blower is required to keep internal parts cool. Since the previous ovens did not require this vent/blower feature, it must be assumed that this is a design flaw in the Kenmore oven (parts not designed for actual operating temperatures, so cooling is required to keep these parts cooler).
Please explain the logic for the need for the vent/blower if different than discussed above, or confirm the above
Thank you

I agree the vent blower adds heat to the kitchen and older model wall ovens did not have a vent blower.

If you look at the size of the oven cavity of your oven and remember the size of the oven cavities of older ovens, you will probably agree the oven cavities are larger today.

The overall size of the built in ovens are about the same as they were 20 years ago. The cut out dimensions are very close to the same.

This has reduced the ability to have a natural draft cooling that keeps the outside walls of the oven from being too hot.

The allowable temperature of the door, controls, and outer walls of an oven are regulated by Underwriters Laboratories (UL) as it has been for at least 35 years. The purpose of this regulation is to make the wall ovens and ranges safe.

Over the years manufacturers have pushed the limits to increase oven sizes. This is because that is what consumers want.

In order to meet UL standards, cooling fans are now installed on most appliances with ovens.

I hope I haven't bored you with a lot of information you already knew. This has been a pet peeve of mine for years.
