What is the problem with the refrigerator if the bottom freezer is not freezing?
The bottom freezer of a 5yr old kenmore is not freezing and the top refrigerator compartment is not cold. The cooling panel at the inner back of the bottom freezer is not cold or frosted over. The fan in the bottom freezer still works and the digital temperature control panel still responds. The compressor still hums, but ssometimes it makes this sharp blade scraping nose when it stops its humming cycle. What could be the issue with it?
