Our Kenmore Upright Frostfree freezer has been working fine for about 8 years. Although the freezer still runs, it only cools to 30-40 degrees. This problem appears to have occurred overnight. The freezer will hold its temperture, just at the higher level. The temperture does swing based on adjustment of the thermostat, with the coldest setting bringing the freezer down to 30 degrees and the warmest setting up to 40 degrees. I have also manually defrosted the unit, but it did not have any effect. What is the likelihood that this can be repaired ecomoically or is there a problem with the sealed system.
