12 year old Kenmore refrigerator cools some, as does the freezer. Freezer does not cool enough to freeze though. I have checked the controls and gasket, both seem to be set correctly and working. The refrigerator is running constantly and I can hear what I believe to be the fan running. I do not hear a clicking sound as described by other questioners. I checked the evaporator fan and it appears to be running at full speed.
