Recently received this appliance from my mother and it worked fine. We got it over to our house (short trip) and plugged it in. Overnight, the freezer only got to 9 degrees. Thinking it was going down, I put all the food in there. Later checked and it was at 14 degrees. WE unplugged it and plugged it back in. Went up to 23 degrees and then overnight back down to 16 degrees. Air in back seems cold but not freezing. Refrigerator finally went down to 37 degrees and is working fine. I took all the food out and the temp went up to 18 degrees. Can hear it working and air coming out but not cold enough.
Is there a quick easy fix or not? Thanks for your time
