Model Number: 59662839200
Brand: Sears Kenmore
Age: 6-10 years

Noticed that the food compartment was warming up on my bottom freezer Kenmore refrigerator.
I could hear a fan blowing inside, but no air coming out of an air register in the food area.
I noticed frost in the freezer (lots of it) against back wall. I unplugged it for 24 hrs, and it worked well for about 10 days--then frosted up again--no air movement in food compartment.
Are there some common problems for this model?
Your help is greatly appreciated.
