Display shows Lo instead of a temperature; unit may be very cold or sensor may be disconnected.

Safety first: Unplug the appliance before accessing the interior panels.

Lo indicates the control is reading a temperature below the sensor's normal range, often due to a shorted or misplaced sensor.

• Step 1 – Check actual temperature: Place an accurate thermometer inside the cabinet to see if the temperature is truly extremely low or if the reading is false.
• Step 2 – Inspect sensor location: Remove shelves and locate the cabinet thermistor. Ensure it is not in direct contact with the evaporator panel or any metal surface that could be much colder than the air.
• Step 3 – Check wiring for shorts: Inspect the sensor wires for damaged insulation or contact with sharp metal edges. Repair or replace damaged wiring.
• Step 4 – Test thermistor: Disconnect the sensor and measure resistance. A very low resistance (near 0 Ω) indicates a shorted sensor that must be replaced.
• Step 5 – Replace sensor: Install a new Café-compatible cabinet thermistor and secure it in the correct location away from direct contact with the evaporator.

Restore power and verify that the display shows a realistic temperature after several minutes.
