I wanted to clean the 10 years worth of dust from it. When I removed the top the fan fell out now I have no idea how it went in there. It just fell right out. I need help to get it working again. Other than that it's been a great microwave that our family depends on & it's been hard being without it for 2 weeks. I really don't want to buy a new one right now I just need to know how to put the fan in place. Thank you, Trina Dowdy
