Work great for three days then heats and will not stay cold. Unplug for a day it will work three more days. I was told it could be the condensor # 5403jj1004a?
The likelihood of the condenser being the issue with the unit is very slim. The issue could most certainly be a issue with a floating restriction in the sealed system, but it could also be the defrost relay sticking on the control board. With a floating restriction, it could be in the filter drier, could be in the evaporator or just somewhere in the line that would cause the unit to stop cooling. In most cases what would normally cause the issue would be a control board or defrost sensor issue that is not allowing the unit to go into the defrost.
