Why does the temperature difference change greatly when the sensor is in the refrigeration layer?

  • Because the temperature of each layer in the refrigeration layer is different, usually from top to bottom in a ladder distribution, so the temperature measured by the sensor in different layers will also be different. And the temperature will also change with the opening of the refrigerator and its own adjustment. The change is usually around 3.6°F~5°F. If the change in temperature is greater than 5°F, please refer to this article .
