I did not know I could change the fan speeds. I just knew that when I switch to manual it runs the fan non stop. Learn something new every day, I missed that part on the Manual.
When I changed the temps I was in the automatic mode and wanted to see how the unit did when changing temps,etc. So in the test I ran it at 350, then changed the set (auto) temp to 250. The unit stopped the fan until the unit cooled to 250, then kept it there as programmed.
I made the mistake of putting too much on the cooking surface, (the large pans) that cut airflow by at least 80%.
Live and learn I guess.
Why yes, you do smell pork!
