Since purchasing our 310RL new in 2021, the refrigerator works fine. However, the freezer must have a mind of its own and has some issue with ice cream. No matter where we put the ice cream in the freezer, it will not keep it frozen. We had our dealer keep it for most of last summer and they replaced the cooling unit and they say everything is up to specs. but it still will not freeze ice cream. Anyone else with this problem? How to resolve? Thank you for your help.
