Guide :Freezers : 20.3 cu. ft. / 575 liter Upright Freezer 23024
Kenmore Freezer Model 23041
Freezer will not stay cold. Last week interior temp came up but went back down on its own (no foods had been added to the freezer at the time to cause the temp increase). This morning, everything is thawed/melted. No other obvious symptoms. Freezer is running, air is circulating, seals are good, just won't maintain temp. Any and all suggestions welcome. Freezer has been very reliable to this point.
