Dual-zone Aobosi wine cooler: one zone cools properly while the other is too warm or too cold.

Safety: Unplug the unit before removing interior panels between zones.

• Compare readings: Use thermometers in both zones to verify actual temperatures versus display.
• Check vents: Ensure that air vents between zones are not blocked by shelves or bottles.
• Inspect zone sensor: Locate and test the NTC sensor for the affected zone as described in sensor-related procedures. Replace if readings are incorrect.
• Air damper (if equipped): Some models use a motorized damper to share cooling. Check that the damper moves freely and is not stuck closed or open. Replace the damper motor if it does not actuate.
• Control board: If hardware is fine but one zone still does not regulate, the zone control circuit on the main PCB may be faulty and require replacement.
