Freezer temperature display is inaccurate compared to an appliance thermometer.

Safety first: Unplug the freezer before accessing the thermistor or control board.

• Step 1 – Confirm with a reliable thermometer: Place a quality appliance thermometer in the center of the freezer for 24 hours and compare to the display.
• Step 2 – Adjust setpoint: If the display reads warmer than actual, raise the set temperature slightly to compensate, and vice versa.
• Step 3 – Inspect thermistor mounting: Ensure the thermistor is firmly clipped in place and not hanging loose.

Persistent large discrepancies indicate a failing thermistor or control board, which should be replaced by a technician.
