Frigidaire Upright Freezer - not working

Frigidaire upright freezer - not in working order so for parts or repair. Stopped freezing at the top of the freezer so have replaced. It was reconditioned when we purchased it about 10 years ago. Plastic covering for second shelf broke when I cleaned it. One of the feet has broken off. Small dent on the inside of door. 213 litres, model N210.
