We were joyful for the new oven to be in our kitchen.  My daughter quickly bake two items in each oven. 2.5 hours for one pan of frozen lasagnas, 15 minutes lower oven for four shrimps.   The baking smell were blown from two ovens and filled the two story house. We need to open all windows and doors at below 10 degree temperature in December 2022. 

I then started to look closer to the design of this new oven.  Fans are built in to blow out of the oven for balancing oven temperature; however this design didn’t come with the idea of ventilation air duct to sucking the faned-air to outside, instead the fan blowing cooking air and smell into kitchen and filling the whole house.

Every time we turn on the oven, we can feel strong wind blowing to our face from inside the oven.  Is this a normal condition to our new oven?
