Evaporator Thermistor
The evaporator thermistor is clipped to the suction
tube line of the evaporator. See
Evaporator
for
accessing instructions.

Replacement
Should a thermistor require replacement, use
plastic bell connectors (part # WR01X10466). Fill
each connector with RTV102 silicone, then splice
a new thermistor into the harness as shown in the
illustration.

Evaporator Fan
The position of the fan blade in relation to the
shroud is important.
Fresh Food and Freezer Light Thermostats
Incandescent fresh food light and freezer light
housings have thermostats that interrupt power to
the lights when the thermostat temperature reaches
175°F. Power is restored when the thermostat
temperature cools to 155°F.
Each thermostat is attached to the back of each
light housing with an 11/32-in. nut.
To access each thermostat, remove the light cover
and light housing. The fresh food light housing is
held in place by 3 Phillips-head screws. The freezer
light housing is held in place by a single Phillips-
head screw.
Note:
It is necessary to remove the freezer light bulb
to access the freezer light housing screw.
Replacement
Should a thermostat require replacement, use
plastic bell connectors (part # WR01X10466). Fill
each connector with RTV102 silicone, then splice a
new thermostat into the harness.

Orifice
The evaporator fan is the same fan used on previous
models; however, a signi
fi
cant difference is that the
main control board neither requires nor receives
input from the fan feedback/rpm (blue) wire. The fan
utilizes a permanent magnet, 4-pole, DC motor that
operates at three different speeds: high, medium,
and low.
The speed of the fan is controlled by the voltage
output from the main control board (J2 pin 4 to J2
pin 3). Voltage output from the main control board
to the fan is 13.6 VDC; however, to regulate the
speed of the fan, the main control board uses pulse
width modulation (PWM).
