Freezer display shows LO or very low temperature reading; food may be excessively frozen or ice crystals form on packaging.

Safety first: Unplug the freezer before accessing any internal components or control boards.

• Step 1 – Check temperature setting: Verify the set temperature on the control panel. For KitchenAid freezers, a typical setting is 0°F (-18°C). Raise the set temperature by 2–4°F and monitor for 24 hours.
• Step 2 – Verify actual temperature: Place an appliance thermometer in the center of the freezer. After 24 hours, compare the reading to the display. If the display shows LO but the thermometer reads near 0°F, the thermistor may be faulty.
• Step 3 – Power reset: Disconnect power for 5 minutes, then plug back in to reset the control. Recheck the display and operation.
• Step 4 – Inspect thermistor connection: Access the thermistor (usually clipped to the evaporator cover or liner wall). Check for loose or corroded connectors. Reseat the plug firmly.

If the freezer continues to run excessively cold or the LO indication persists with a normal interior temperature, the thermistor or main control board likely needs replacement. This diagnosis typically requires resistance measurements and should be done by a technician.
