Possible Causes

Inter-zone fan not operating, Blocked air channels, Incorrect sensor calibration, Overloading one zone with warm bottles

How to Fix / Troubleshooting

Safety first: Unplug before accessing internal fans or panels.

  • Balance loading: Avoid overloading one zone while leaving the other nearly empty. Distribute bottles more evenly.
  • Check inter-zone fan: On dual-zone Phiestina models, verify that the "Inter-zone circulation fan" runs when both zones call for cooling. Replace if not operating.
  • Clear air channels: Ensure vents between zones are not blocked by bottles or shelves.
  • Sensor check: Compare displayed temperatures with a separate thermometer in each zone. Replace any "Zone temperature sensor" that reads inaccurately.
