Freezer thermistor
The freezer Thermistor is a variable resistance device connected to the control board. The
temperature of the freezer compartment causes the resistance of the Thermistor to change.
The resistance is monitored by a circuit on the control board which controls the operation of
the cooling system. The Thermistor is located on the left side of the freezer cabinet attached to
the back of the cover labeled 6
