The T18IW905SP holds 58 bottles in an 18-inch Freedom column, two more than the 800-generation T18IW800SP, and splits them into two independent zones. Thermador’s product page highlights Wenge wood diamond dowels on hidden rails that cradle each bottle.
Since each zone is controlled on its own, a single zone that will not hold temperature points to that zone’s sensor, fan or air path rather than the whole column. Racks carrying full bottles are heavy for their rails, and forcing a sticking rack can damage it.
