Possible Causes

Oversensitive temperature sensor placement, Control board hysteresis too narrow, Refrigerant charge issue, Poor ventilation causing rapid temperature swings

How to Fix / Troubleshooting

Safety first: Frequent cycling can shorten compressor life. Address promptly.

  • Improve ventilation: Ensure vents are clear and the unit has proper clearance. Overheating can cause rapid cycling.
  • Check sensor placement: Verify the "Cabinet temperature sensor" is properly mounted away from direct airflow from the evaporator and not touching cold metal, which can cause false readings.
  • Stabilize load: Avoid frequent door openings and large, rapid changes in bottle load.
  • Control board replacement: If cycling remains abnormally frequent, the "Main control board" may have faulty logic and require replacement.
  • Professional check: A refrigeration technician can verify refrigerant charge and system performance if mechanical issues are suspected.
