Possible Causes

Temperature sensor located too close to cold air outlet, Control PCB hysteresis too narrow, Poor air circulation due to overloading, Ambient temperature fluctuations

How to Fix / Troubleshooting

Safety: Unplug the unit before moving sensors or adjusting internal components.

Steps to reduce short cycling:

  • Improve air circulation: Avoid blocking air vents with bottles and do not overpack shelves.
  • Check sensor placement: Ensure the cabinet sensor is not directly in the path of cold air from the evaporator outlet. Reposition slightly if possible.
  • Stabilize environment: Avoid placing the wine cooler in areas with large temperature swings or direct sunlight.
  • Control board: If cycling remains excessive and affects temperature stability, the control PCB may need firmware update or replacement, which must be done by a technician.

Note: Some cycling is normal, but very short, frequent cycles can reduce compressor life.
