The T48IT102NP is the largest French-door combination column Thermador currently lists, at 48 inches wide with 26.8 cu ft total capacity (17.7 cu ft refrigerator / 9.1 cu ft freezer) and roughly 677 lb gross weight. At this width, the two fresh-food doors are the widest in the French-door lineup, which makes hinge alignment and center-mullion sealing more sensitive to an out-of-level cabinet than on the narrower 36- and 42-inch versions – installation leveling is worth double-checking on any service call involving a seal complaint.
It shares its internal water dispenser, UltraClarityPro filter, and ice maker (rated 4.5 lb/24hr, 6 lb storage) with the rest of the IT-series columns, so dispenser and ice troubleshooting should start with the filter cartridge and refill presets rather than the valve or control board. Because the refrigerator and freezer sections run as independent zones, a temperature problem isolated to one side should be diagnosed against that section’s own compressor and controls.
