Freezer Evaporator Thermistor - GEAppliances CFE28TSH Technical Service Manual

The freezer evaporator thermistor is attached to
the inlet tube with a metal clip. The purpose of the
thermistor is to monitor the evaporator temperature
for defrost control.
To access the freezer evaporator thermistor the
freezer evaporator cover must be removed (see the
Freezer Evaporator Cover section).
The ice box fan wire connector also contains
the freezer evaporator thermistor connections. The
freezer evaporator thermistor can be replaced
separately ( : WR55X10025).
When replacing the freezer thermistor:
1. Place the replacement thermistor next to the
original thermistor.
2. Cut the wiring at a location that will match the
original length when the replacement thermistor
is spliced to it.
3. Use plastic bell connectors (
WR01X10466). Fill each connector with silicone
grease, then splice a new thermistor into the
harness as shown in the illustration.

The ice box fan is located at the top left rear of the
freezer compartment above the evaporator. The ice
box fan circulates air into the left fresh food door ice
box via duct work foamed into the case.

The fan will operate at three speeds with RPM
feedback to the control. Speeds selected depend on
the ice box cooling temperature and are controlled
by the main board. The speed range is 1500 RPM -
2300 RPM.
