A compressor or refrigerant-system problem (F8) on a Liebherr wine cabinet can raise cabinet temperature by 3-5°F per hour in a typical room environment once cooling capacity is impaired — fast enough that a collection can drift meaningfully outside its safe range within a matter of hours, not days. That’s part of why we treat these calls with more urgency than the equivalent problem would get on a kitchen refrigerator, where the stakes and the pace of temperature change are both lower.
If you have alternate temperature-controlled storage available for anything particularly valuable or heat-sensitive, moving it there while waiting for the repair is a reasonable precaution — but the underlying fix still needs a technician with the right refrigerant-handling equipment.
