Dual-zone wine cooler: one zone warm, the other fine

When one zone of a dual-zone cooler works, the compressor or main cooling is usually alive. Focus on what each zone has on its own: its sensor, its fan, its air path or damper, its door seal and its section of the control.

Thermoelectric wine cooler not cooling (fans run, cabinet near room temperature)

Thermoelectric coolers move heat with a solid-state Peltier module and two heat-sink fans, so they can only pull the cabinet a limited amount below room air. Rule out a hot room, blocked airflow and dusty fins before condemning the module, its fans or the DC power supply.

Wine cooler too cold or bottles freezing

Over-cooling comes from a cold room (especially with thermoelectric units, which have no heater), an iced evaporator, a blocked internal fan, or a failed sensor/control.
