Wine Enthusiast wine cooler cycles on and off frequently, with short run times and unstable temperature.

Safety: Unplug the unit before adjusting sensors or controls.

• 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: Move the cooler away from direct sunlight, HVAC vents, or exterior doors that cause rapid ambient changes.
• Verify setpoint: Avoid setting the temperature extremely close to ambient; provide a reasonable difference to reduce cycling.
• Test sensor: Replace the cabinet temperature sensor if it shows erratic resistance readings.
• Control board replacement: If short cycling persists with a good sensor and stable environment, the control board may be misreading or miscontrolling and should be replaced.
