Temperature display does not match actual bottle temperature.

Safety: Unplug before accessing interior panels or sensors.

Steps:

• Verify with thermometer: Place an accurate thermometer in the center of the zone and compare after several hours.
• Adjust loading: Avoid blocking vents or packing bottles tightly around the sensor area.
• Check sensor placement: Ensure the sensor is mounted as designed and not hanging loose.
• Replace sensor: If readings are consistently off by several degrees, replace the cabinet temperature sensor.
• Control board: Persistent large discrepancies after sensor replacement may indicate a control board calibration issue requiring board replacement.
