Guide :Freezers : 7 cu. ft. / 198 liter Commercial Freezer ULT27
Traulsen freezer URS48DT
My freezer keeps overfreezing. To work at all, I have to defrost the freezer - then it works for about two weeks, then freezes over and doesn't work anymore. I'm de-frosting again tonight. What is wrong? The refrigerator works just fine.
