How to Fix / Troubleshooting

Safety: Unplug before accessing internal components.

  • Compare zones: Verify which zone is not cooling and note any error indicators on that zone's display.
  • Check airflow: Ensure vents between zones are not blocked by bottles.
  • Inspect zone fan/damper: Access the partition between zones and test the zone fan motor or air damper. Replace if not operating.
  • Test zone sensor: Measure resistance of the affected zone's sensor and replace if defective.
  • Control board: If hardware is good, the dual‑zone control board may have a failed output for that zone and should be replaced.
