Della Marta Temperature Calibration or Sensor Drift

Temperature display is inaccurate compared to a separate thermometer inside the cabinet.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Aging NTC sensor, Sensor not in correct airflow, Control board calibration offset, Sensor wiring resistance change

Safety: Unplug the unit before accessing sensors.

Verify with reliable thermometer: Place a calibrated thermometer in the center of the cabinet away from walls and compare readings.
Check sensor placement: Ensure the cabinet NTC sensor is positioned in free air, not touching walls or bottles.
Replace sensor: If the display is consistently off by several degrees, replace the cabinet NTC sensor.
Control board: If a new sensor does not correct the reading, the main control PCB may have a calibration fault and should be replaced.
