Freezer temperature display does not match actual temperature measured with a thermometer.

Safety: Unplug the unit before accessing sensors.

• Verify with multiple thermometers: Place a reliable thermometer in the center of the freezer and compare readings over several hours.
• Check sensor placement: Access the freezer compartment sensor and ensure it is properly mounted and not hanging loose.
• Replace sensor: If readings are consistently off, replace the Samsung freezer temperature sensor.
• Check airflow: Avoid blocking vents with food, which can cause uneven temperatures.
• PCB calibration: If a new sensor does not correct the discrepancy, the main PCB may be miscalibrated and require replacement.
