Fresh Food Thermistor
The unit uses a thermistor (type of resistor
whose resistance varies with temperature) to
control temperature. The temperature of the
thermistor equates to a resistance that is fed
back to the low voltage control board. Refer
to resistance vs. temperature chart on page
11 and Cut-in and Cutout temperature chart
on page 35.
To access the thermistor, open the
refrigerator door, remove the upper
shelf, remove the screws securing it, and
disconnect the wiring.
In order to check the thermistor, refer to All
Refrigerator Programing on page 24 to check
the thermistor.

circulate air through the refrigerator.
1. To access the lower fresh food fan,
remove all shelves and drawers.
