Been a great fridge.
Last night small water drops on back panel. Ear to door and compressor is working. If fridge not used for a while, small ice drops form on back panel but if preparing dinner and door is open and shut often, water drops reappear on back panel till you leave it again for a while. I suspect defrost circuit maybe??????? Can the DF Timer be tested/changed easily and where is it located?
