User Guide

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 thermis-
tor 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 refriger-
ator 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.
