Used the actual oven for the first time the other day.  Selected the temperature and once I hit the bake button something in the bottom backside started making a awful sound.  Sounded like a fan or blower motor was on its last leg.  Continued to run the whole warmup, cook time, and till it decided it was cool enough.  Haven’t gotten a hold of Frigidaire yet so not sure how their customer service is but sad you have to call or have something like this happen on a brand new appliance that you had for less than a month.
