Help, this is a top freezer model, ge TBX18DAXHRWW. The exterior left side of freezer where freezer door shuts gets very hot-just a small area but hot enough to melt items in freezer door bin. This lasts about 45 minutes and then the area gets cold for about another 45 minutes and then gets hot again. The area is small but hot enought to melt or soften the frozen items in the freezer.
The refrig is too warm-about 55 degrees.
Any suggestions as to what parts might need to be replaced?
