Model Number: FFFU20F2VWO
Brand: Frigidaire
Age: 1-5 years

I have a Frigidaire FFFU20F2VWO upright garage freezer that I have owned for a few years now. Two or three times now the evaporator fan has frozen up, resulting in the food on the top defrosting. I remove the evaporator cover and defrost the fan with a heat gun and then it runs fine for a while until it happens again. I am wondering if someone can tell me what the underlying problem is that is causing the fan to freeze up so I can permanently fix the problem. Thank you!
