Possible Causes

Temperature sensor located too close to evaporator, Oversensitive control algorithm, Poor air circulation around sensor, Incorrect thermostat placement after repair

How to Fix / Troubleshooting

Safety: Unplug the unit before moving sensors or panels.

Steps:

  • 1. Observe cycling: Note how long the compressor runs and rests. Very short cycles (1–3 minutes) are undesirable.
  • 2. Check sensor location: Remove the inner panel and verify the sensor is in the correct factory position, not touching the evaporator or walls.
  • 3. Improve airflow: Ensure shelves and bottles do not block airflow around the sensor.
  • 4. Replace sensor: If the sensor is erratic, replace the cabinet NTC sensor.
  • 5. Control board: If short cycling persists, the control board may be misbehaving and require replacement.
