Possible Causes

Failed evaporator fan in affected zone, Faulty NTC sensor for that zone, Air duct blockage between zones, Control PCB not activating that zone's cooling circuit

How to Fix / Troubleshooting

Safety: Unplug the appliance before accessing interior panels or fans.

Steps to diagnose a warm zone:

  • Compare zones: Verify that the set temperatures are correct for both zones and that doors are sealing properly.
  • Check fan operation: Listen for the evaporator fan in the warm zone when the compressor is running. If silent, access and test/replace the fan motor.
  • Inspect air ducts: Ensure that any air passages between zones are not blocked by bottles or debris.
  • Test zone sensor: Measure the NTC sensor for the warm zone and replace if out of specification.
  • Control PCB: If hardware is good but the zone never cools, the control PCB may not be energizing that zone's valve or circuit and may need replacement.

Note: Some SMEG dual-zone models share a compressor but use separate fans and sensors; correct diagnosis depends on the specific design.
