Yes — packing a wine cabinet beyond its rated capacity, or arranging bottles in a way that blocks internal airflow between shelves, can produce the same kind of temperature instability signs as an actual sensor or cooling-system problem, without anything having genuinely failed. Liebherr’s cabinets are designed around a specific internal air circulation pattern to keep temperature consistent across every shelf, and overloading disrupts that.
If you’re seeing a TEMP SWING alert or general inconsistency and the cabinet is at or near full capacity, it’s worth checking whether shelf spacing and airflow are part of the cause before assuming a part has failed — something our technicians rule out as part of any diagnostic.
