Auto fan comes on immediately every time!

We just got a free replacement over the range GE microwave as the old one took a crap. The auto fan comes on every single time as soon as I shut the door to start cooking something. Of course the fan is loud so it’s extremely annoying. I thought the auto fan was only supposed to come on if it got too hot inside. Any ideas??
