Display shows Lo instead of a temperature; cabinet feels very cold or sensor is not detected.

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

Cabinet temperature below minimum measurable value, Shorted NTC sensor, Control board miscalibration, Ambient temperature too low

Safety: Protect your wine from freezing. If bottles show signs of ice, unplug the unit.

Measure actual temperature: Place a thermometer inside to confirm if the cabinet is truly below the normal range.
Check ambient: If the room is very cold, move the cooler to a warmer location.
Test NTC sensor: If the cabinet is not extremely cold but Lo is displayed, test the NTC for a short circuit. Replace if necessary.
Reset and monitor: Power-cycle the unit and observe whether normal temperature readings return. If not, the control board may require replacement.
