Ice Box Fan; Freezer Evaporator Thermistor - GE Adora DFE29JG Technical Service Manual

Freezer Evaporator Thermistor

The freezer evaporator thermistor is attached to the
suction line 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
.)
Freezer Evaporator Cover
Note: The ice box fan wire connector also contains
the freezer evaporator thermistor connections. The
freezer evaporator thermistor can be replaced
separately (Part #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 (Part # WR01X10466).
Fill each connector with silicone grease then
splice a new thermistor into the harness as
shown in the illustration.

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 3 speeds with RPM feedback
to the control. Speeds selected depend on the ice
box cooling temperature and are controlled by the
main board. Approximate fan speeds are:
Low Speed = 1500 RPM
Medium Speed = 1800 RPM
High Speed = 1800 RPM
