Design ■ Features ■ Performance

When checking the thermistors to see if they are reading accurately, it is common to place them in an icebath to see if they read 32°F. Do not place them directly in the water. Use a plastic bag to protect them from moisture. The freezer and ice maker should read 32°F in icewater, however the refrigerator thermistor should read 36°F. There is a built-in 4°F offset in this reading due to its location in the cabinet. This sensor is located outside the refrigerator drawer, which is approximately 4°F colder than the inside of the drawer.

To check the actual temperatures via the display, touch and release the warmer button to view the refrigerator temperature. Hold the colder button, while LED 1 is lit, the freezer temperature will be displayed. Continue holding the colder button, and the display will cycle from freezer to ice maker until the button is released.
