A proximity sensor is installed on the bottom of the refrigerator door. If dust builds up on the proximity sensor, it may affect sensor performance. Clean the sensor regularly. Use a clean sponge or soft cloth and a mild detergent in warm water. Do not use glass cleaners, abrasive cleansers, or flammable fluids. These can scratch or damage the material. Dry with a paper towel to avoid streaks.
