Wine cooler cycles on and off very frequently (short cycling).

Safety: Unplug the unit before accessing sensors or compressor components.

Steps:

• Verify ambient conditions: Avoid placing the wine cooler near heat sources or in direct sunlight.
• Check thermistor placement: Ensure the cabinet thermistor is not directly in the cold air stream from the evaporator fan; reposition slightly if necessary.
• Monitor compressor: Listen for rapid on/off cycling with clicks from the compressor area. If present, inspect and replace the start relay/overload as needed.
• Control board: If mechanical components are fine but cycling remains excessive, the control board may be mismanaging compressor run times and could require replacement.
