Possible Causes

Temperature sensor located too close to evaporator, Oversensitive control algorithm, Poor ventilation around unit, Oversized unit for small space

How to Fix / Troubleshooting

Unplug the cooler before moving sensors or panels.

  • 1. Improve ventilation:
    • Ensure adequate clearance around the cooler per Lanbo specifications.
  • 2. Check sensor placement:
    • Access the cabinet sensor and ensure it is not directly in the cold air stream from the evaporator.
    • Reposition slightly if necessary.
  • 3. Verify setpoint:
    • Avoid setting the temperature extremely close to ambient room temperature, which can cause frequent cycling.
  • 4. If cycling persists:
    • The main control board may have overly aggressive control logic or a fault; replacement may be required.
