Need advice on Kenmore upright freezer
I have a Kenmore upright freezer, model number 253.21421105.
It is in a semi-finished basement, used regularly, and is kept clean.
In the past few days it has stopped cooling and the food has started to thaw. The fan works fine (air is flowing out of the vents in the back top). The compressor is very warm, and seems to be working. However, the sides of the freezer, in which the coils sit, used to get cool, but they no longer do.
Any hints? Or is it time to just go buy a new one.
Thanks in advance.
