Fresh Food Thermistor; Lower Fan Assembly - Viking VCRB5301 Service Manual

Disassembly
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.

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
