Sub-Zero Wine Cooler Evaporator Coil Replacement
In this video, Max from MAX Appliance Repair restores a Sub-Zero dual-zone wine cooler with a sealed-system refrigerant leak. Both evaporator coils and the filter-drier were replaced. Because this was a custom installation with the condensing equipment located in a separate basement mechanical room, the system was pressure-tested with nitrogen, evacuated, and carefully charged based on actual system performance.
