Possible Causes

Failed zone-specific thermistor, stuck air damper (if used), blocked air channel, partial sealed system issue affecting one evaporator

How to Fix / Troubleshooting

Safety: Unplug the unit before accessing internal components.

  • Compare zones: Note which zone (upper or lower) is not cooling. Verify its set temperature is lower than room temperature.
  • Check airflow: Ensure bottles are not blocking vents between zones or at the back wall.
  • Test zone thermistor: Access and test the thermistor for the affected zone. Replace if out of specification.
  • Inspect damper (if equipped): Some models use a motorized damper to share cold air. Check that the damper door moves freely and the motor operates. Replace if stuck or inoperative.
  • Sealed system: If one evaporator coil remains warm while the other frosts normally, a sealed system issue may exist and requires professional service.
