The T42IT100NP scales Thermador’s French-door bottom-freezer column up to 42 inches wide, with 23.1 cu ft total capacity split 15.3 cu ft refrigerator and 7.8 cu ft freezer – noticeably more than the 36-inch T36IT100NP’s 18.8 cu ft, aimed at kitchens that want a single combination unit rather than separate refrigerator and freezer columns. At roughly 617 lb, it shares the same French-door mullion alignment sensitivity as the narrower T36IT100NP: door sag or an out-of-level cabinet shows up first as a gap at the center seam rather than at the outer door edges.
Its internal water dispenser, UltraClarityPro filter, and ice maker (rated 4.5 lb/24hr, same as the 36-inch model) run through the same plumbing architecture as the rest of the IT-series columns, so dispenser troubleshooting should start with the filter cartridge and refill presets. Given the freezer and refrigerator sections operate as independent zones, a temperature complaint isolated to one side points to a section-specific problem rather than the shared cabinet.
