Quick Assessment

Answer to continue safely

Is it safe to keep using?

Maybe. If the actual temperature is acceptable (verify with a thermometer), wine is safe. The zone just cannot be independently controlled.

Can I reset the code?

Yes. A power cycle clears the error. A failed sensor will retrigger the code.

When to stop immediately?

Stop if you notice: Actual temperature is outside wine storage range, Both zones are uncontrolled.

Symptoms You May Notice

Lower zone temperature is unstable

The lower compartment temperature varies significantly from the set point.

Lower zone display is incorrect

The temperature display for the lower zone shows dashes or an unrealistic reading.

Both zones seem to run at the same temperature

Without a working lower sensor, the lower zone may default to the upper zone temperature.

Possible Causes

1

Failed lower zone thermistor

The sensor element for the lower zone has failed.

Requires Professional
2

Sensor wiring fault

A wire break or loose connection between the sensor and the control board.

Safe Checks You Can Do

  1. 1

    Power cycle the cooler

    Unplug for 5 minutes and check if the reading normalizes.

    Place a thermometer in the lower zone to monitor the actual temperature.

  2. 2

    Monitor with external thermometer

    Place a wine or food thermometer in the lower zone to track actual temperature.

    If actual temperature stays in the 50-60°F range, wine is safe temporarily.
