Non Working 3.7 QT Air Fryer (Fern Park)

This fairly new but previously used Ambiano Air Fryer was sold to me as an Open Box working unit but after getting it home I found while the heating element works fine, the fan does not turn even though the display shows it as working. (I did get a refund but they didn't want the unit back.) Before I trash it, I wanted to offer it in case someone out there would like to try to fix it. The user manual is included.
