A customer has Sub Zero 427RG Refrigerator/wine cooler combo. Refrigerator unit was not cooling, there was 65 degree inside. We test pressure for the sealed system and find the refrigerant leak on the evaporator coil. We offered to replace the evaporator coil, replace dryer filter and refill refrigerant. First, we remove all sliders, panels and side panels to have access to the evaporator coil. Then we cut old coil and weld new one. After we replace old dryer filter with new one. We created the vacuum and refill refrigerant with the proper amount specified on the label.
Another happy customer!
